当有电话呼入时，电话线上传输的25HZ、90V 的交流振铃信号由C1、C2隔离直流后由整流桥整流，整流后的直流电压值较高，经光电隔离器U1后输出TTL脉冲信号，该脉冲经74LS123整形成大方波信号，该方波信号送至单片机的P3.5引脚进行计数，当计数值达到预设值时，单片机P1.0引脚输出高电平，三极管Q1导通则继电器K1动作，将负载电阻R5（330Ω）接入电路实现模拟摘机。

这里所说的模拟摘机是指将R5接入电路后，电话线上就会出现大于10mA的电流，交换中心检测到这一电流后就不再输出振铃信号而是转为接通电话。

人们手动摘机接通电话时的工作过程与此一致，因此称为模拟摘机。

如果振铃信号没有达到预设值就消失，则单片机的计数值清零，控制器不动作。

HD74AC165/HD74ACT165Parallel-Load 8-bit Shift RegisterADE-205-374 (Z)1st. EditionSep. 2000 DescriptionThis 8-bit serial shift register shifts data from QA to QHwhen clocked, Parallel inputs to each stage areenabled by a low level at the Shift/Load Input. Also included is a gated clock input and a complementary output from the eighth bit.Clocking is accomplished through a 2-input NOR gate permitting one input to be used as a clock inhibit function. Holding either of the clock inputs high inhibits clocking, and holding either clock input low with the Shift/Load input high enables the other clock input. Data transfer occurs on the positive going edge of the clock. Parallel loading is inhibited as long as the Shift/Load input is high. When taken low, data at the parallel inputs is loaded directly into the register independent of the state of the clock.Features• Outputs Source/Sink 24 mA• HD74ACT165 has TTL-Compatible InputsHD74AC165/HD74ACT1652Pin ArrangementLogic SymbolPin NamesA to H Parallel Inputs S I Serial Input CP Clock Input S LShift Load Clock Inhibit Clock Inhibit Q H , Q HOutputsHD74AC165/HD74ACT1653Truth TableInputsClockParallel Internal Outputs Outputs S L Inhibit CP S I A ······ H Q A Q B Q H L X X X a ······ h a b h H L LX X Q A D Q B O Q HO HL H X H Q An Q Gn HL L X L Q An Q Cn H HXXXQ A DQ B OQ HOH :High Voltage Level L :Low Voltage Level X :Immaterial: Low-to-High Clock TransitionHD74AC165/HD74ACT1654Logic DiagramDC Characteristics (unless otherwise specified)ItemSymbol Max Unit ConditionMaximum quiescent supply current I CC 80µA V IN = V CC or ground, V CC = 5.5 V,Ta = Worst caseMaximum quiescent supply current I CC 8.0µA V IN = V CC or ground, V CC = 5.5 V,Ta = 25°CMaximum additional I CC /input (HD74ACT165)I CCT1.5mAV IN = V CC – 2.1 V, V CC = 5.5 V,Ta = Worst caseHD74AC165/HD74ACT1655AC Characteristics: HD74AC165Ta = +25°C C L = 50 pFTa = –40°C to +85°C C L = 50 pF ItemSymbol V CC (V)*1Min Typ Max Min Max Unit Maximum count f max3.385——70—MHzfrequency 5.0100——90—Propagation delay t PLH 3.3 1.011.017.5 1.020.5ns CP to Q H or Q H 5.0 1.08.011.5 1.013.5Propagation delay t PHL 3.3 1.012.018.0 1.021.5ns CP to Q H or Q H 5.0 1.08.512.5 1.014.5Propagation delay t PLH 3.3 1.013.519.5 1.022.5ns H to Q H or Q H 5.0 1.09.513.5 1.015.5Propagation delay t PHL 3.3 1.09.014.0 1.016.5ns H to Q H or Q H 5.0 1.0 6.59.5 1.011.0Propagation delay t PLH 3.3 1.011.520.5 1.023.5ns S L to Q H or Q H 5.0 1.08.514.0 1.016.0Propagation delay t PHL 3.3 1.010.016.5 1.019.5ns S L to Q H or Q H 5.01.07.511.01.012.5Note:1.Voltage Range 3.3 is 3.3 V ± 0.3 VVoltage Range 5.0 is 5.0 V ± 0.5 VHD74AC165/HD74ACT1656AC Operating Requirements: HD74AC165Ta = +25°C C L = 50 pFTa = –40°C to +85°C C L = 50 pFItemSymbol V CC (V)*1Typ Guaranteed MinimumUnit Setup time, HIGH or LOW t su3.3 3.5 5.0 6.0nsH to S L5.0 2.5 4.0 4.5Hold time, HIGH or LOW t h3.3–1.00.50.5ns H to S L5.0–0.50.50.5Setup time, HIGH or LOW t su 3.3 1.0 3.5 4.0ns S in to CP5.00.5 3.0 3.5Hold time, HIGH or LOW t h 3.3 1.5 2.0 2.0ns S in to CP5.0 1.0 2.0 2.0Setup time, HIGH or LOW t su 3.3 3.0 5.06.0ns S L to CP5.0 2.0 4.0 4.5Hold time, HIGH or LOW t h 3.3–2.00.00.0ns S L to CP5.0–1.00.00.0Recovery time clock inhibit t rec 3.3 2.5 3.5 3.5ns to CP5.0 2.0 3.0 3.0Clock pulse width t w 3.3 3.0 5.57.0ns 5.03.04.55.0Note:1.Voltage Range 3.3 is 3.3 V ± 0.3 VVoltage Range 5.0 is 5.0 V ± 0.5 VHD74AC165/HD74ACT1657AC Characteristics: HD74ACT165Ta = +25°C C L = 50 pFTa = –40°C to +85°C C L = 50 pF ItemSymbol V CC (V)*1Min Typ Max Min Max Unit Maximum count frequency f max 5.070——60—MHz Propagation delay CP to Q H or Q H t PLH 5.0 1.08.513.5 1.015.5ns Propagation delay CP to Q H or Q H t PHL 5.0 1.09.514.0 1.016.5ns Propagation delay H to Q H or Q H t PLH 5.0 1.010.513.5 1.015.5ns Propagation delay H to Q H or Q H t PHL 5.0 1.07.511.0 1.012.5ns Propagation delay S L to Q H or Q H t PLH 5.0 1.09.515.0 1.018.0ns Propagation delay S L to Q H or Q H t PHL5.01.08.513.01.015.5nsNote:1.Voltage Range 5.0 is 5.0 V ± 0.5 VHD74AC165/HD74ACT1658AC Operating Requirements: HD74ACT165Ta = +25°C C L = 50 pFTa = –40°C to +85°C C L = 50 pFItemSymbol V CC (V)*1Typ Guaranteed MinimumUnit Setup time, HIGH or LOW H to S Lt su 5.0 3.0 4.0 4.5ns Hold time, HIGH or LOW H to S Lt h 5.0–1.00.00.0ns Setup time, HIGH or LOW S in to CPt su 5.00.5 3.0 3.5ns Hold time, HIGH or LOW S in to CPt h 5.00.5 2.0 2.0ns Setup time, HIGH or LOW S L to CPt su 5.0 2.0 4.0 4.5ns Hold time, HIGH or LOW S L to CPt h 5.0–1.50.00.0ns Recovery time clock inhibit to CPt rec 5.0 2.0 3.0 3.0ns Clock pulse width t w5.03.57.08.0nsNote:1.Voltage Range 5.0 is 5.0 V ± 0.5 VCapacitanceItemSymbol Typ Unit Condition Input capacitanceC IN 4.5pF V CC = 5.5 V Power dissipation capacitanceC PD50pFV CC = 5.0 VHD74AC165/HD74ACT165 Package Dimensions9HD74AC165/HD74ACT16510HD74AC165/HD74ACT16511Cautions 1.Hitachi neither warrants nor grants licenses of any rights of Hitachi’s or any third party’s patent,copyright, trademark, or other intellectual property rights for information contained in this document.Hitachi bears no responsibility for problems that may arise with third party’s rights, includingintellectual property rights, in connection with use of the information contained in this document.2.Products and product specifications may be subject to change without notice.

HD74ALVCH16237316-bit Transparent D-type Latches with 3-state OutputsADE-205-179 (Z)Preliminary1st. EditionDecember 1996 DescriptionThe HD74ALVCH162373 is particularly suitable for implementing buffer registers, I/O ports, bidirectional bus drivers, and working registers. It can be used as two 8-bit latches or one 16-bit latch. When the latch enable (LE) input is high, the Q outputs follow the data (D) inputs. When LE is taken low, the Q outputs are latched at the levels set up at the D inputs. Active bus hold circuitry is provided to hold unused or floating data inputs at a valid logic level. All outputs, which are designed to sink up to 12 mA, include 26Ω resistors to reduce overshoot and undershoot.Features• V CC = 2.3 V to 3.6 V• Typical V OL ground bounce < 0.8 V (@V CC = 3.3 V, Ta = 25°C)• Typical V OH undershoot > 2.0 V (@V CC = 3.3 V, Ta = 25°C)• High output current ±12 mA (@V CC = 3.0 V)• Bus hold on data inputs eliminates the need for external pullup / pulldown resistors• All outputs have equivalent 26 Ω series resistors, so no external resistors are required.HD74ALVCH1623732Function TableInputs Output QOE LE D L H H H L H L L L L X Q 0 *1HXXZ H : High level L : Low level X : ImmaterialZ : High impedanceNote: 1.Output level before the indicated steady state input conditions were established.HD74ALVCH162373 Pin Arrangement3HD74ALVCH1623734Absolute Maximum RatingsItemSymbol Ratings Unit ConditionsSupply voltage V CC –0.5 to 4.6V Input voltage *1V I –0.5 to 4.6V Output voltage *1, 2V O –0.5 to V CC +0.5V Input clamp current I IK –50mA V I < 0Output clamp current I OK ±50mA V O < 0 or V O > V CC Continuous output current I O ±50mAV O = 0 to V CC ±100Maximum power dissipation at Ta = 55°C (in still air) *3P T 0.85W TSSOPStorage temperature Tstg–65 to 150°CNotes:Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device.

After the multivibrator has been retrigger ed com-parator C1and C2start operating and Qn is turned on.Cx then discharges through Qn.The voltage at the node R/C external falls.When it reaches V REFL the output of comparator C1 becomes low.This in turn resets the flip-flop and Qn is turned off.At this point C1stops functioning but C2continues to operate.The voltage at R/C external begins to rise with a time constant set by the external components Rx,Cx. Triggering the multivibrator causes Q to go high after internal delay due to the flip-flop and the gate.Q re-mains high until the voltage at R/C external rises again to V REFH.At this point C2output goes low and O goes low.C2stop operating.That means that after triggering when the voltage R/C external re-turns to V REFH the multivibrator has returned to its MONOSTABLE STATE.In the case where Rx⋅Cx are large enough and the discharge time of the ca-pacitor and the delay time in the I.C.can be ignored, the width of the output pulse tw(out)is as follows: t W(OUT)=0.46Cx⋅Rx(HC123)t W(OUT)=Cx⋅Rx(HC123A)M54/M74HC123/123A3/14FUNCTIONAL DESCRIPTION(continued)RE-TRIGGERED OPERATIONWhen a second trigger pulse follows the first its ef-fect will depend on the state of the multivibrator.If the capacitor Cx is being charged the voltage level of R/C external falls to Vrefl again and Q remains high i.e.the retrigger pulse arrives in a time shorter than the period Rx⋅Cx seconds,the capacitor charging time constant.If the second trigger pulse is very close to the initial trigger pulse it is ineffective ;i.e.the second trigger must arrive in the capacitor discharge cycle to be ineffective;Hence the mini-mum time for a second trigger to be effective de-pends on V CC and Cx.RESET OPERATIONCL is normally high.If CL is low,the trigger is not ef-fective because Q output goes low and trigger con-trol flip-flop is reset.Also transistor Op is turned on and Cx is charged quicky to V CC.This means if CL input goes low,the IC becomes waiting state both in operating and non operatin g state.TRUTH TABLEINPUTS OUTPUTSNOTEA B CL Q QH H OUTPUT ENABLEX L H L H INHIBITH X H L H INHIBITL H OUTPUT ENABLE L H OUTPUT ENABLE X X L L H INHIBITX:Don’t Care Z:High ImpedanceINPUT AND OUTPUT EQUIVALENT CIRCUITM54/M74HC123/123A4/14PIN DESCRIPTIONPIN No SYMBOL NAME AND FUNCTION 1,91A,2A Trigger Inputs(NegativeEdge Triggered) 2,101B,2B Trigger Inputs(PositiveEdge Triggered)3,111CLR,2CLR Direct Reset LOW and Trigger Action at Positive Edge4,121Q,2Q Outputs(Active LOW) 72R EXT/C EXT External ResistorCapacitor Connection 13,51Q,2Q Outputs(Active HIGH)14,61C EXT2C EXT External Capacitor Connection151R EXT/C EXT External ResistorCapacitor Connection8GND Ground(0V)16V CC Positive Supply VoltageIEC LOGIC SYMBOLABSOLUTE MAXIMUM RATINGSymbol Parameter Value Unit V CC Supply Voltage-0.5to+7V V I DC Input Voltage-0.5to V CC+0.5V V O DC Output Voltage-0.5to V CC+0.5VI IK DC Input Diode Current±20mAI OK DC Output Diode Current±20mAI O DC Output Source Sink Current Per Output Pin±25mAI CC or I GND DC V CC or Ground Current±50mAP D Power Dissipation500(*)mW T stg Storage Temperature-65to+150o C T L Lead Temperature(10sec)300o C Absolute Maximum Ratings are those values beyond whichdamage to the device may occu r.Functiona l ope ration und er these cond ition isnotimplied.

HD74LV123ADual Retriggerable Monostable MultivibratorsADE-205-258C (Z)4th EditionJanuary 2001 DescriptionThe HD74LV123A features output pulse-duration control by three methods. In the first method, the A input is low and the B input goes high. In the second method, the B input is high and the A input goes low. In the third method, the A input is low, the B input is high, and the clear (CLR) input goes high.The basic pulse duration is programmed by selecting external resistance and capacitance values.The external timing capacitor must be connected between Cext and Rext/Cext (positive) and an external resistor connected between Rext/Cext and VccTo obtain variable pulse durations, connect an external variable resistance between Rext/Cext and Vcc. Once triggered, the basic pulse duration can be extended by retriggering the gated low-level-active (A) or high-level-active (B) input. Pulse duration can be reduced by taking CLR low.Features•V CC = 2.0 V to 5.5 V operation•All inputs V IH (Max.) = 5.5 V (@V CC = 0 V to 5.5 V)•All outputs V O (Max.) = 5.5 V (@V CC = 0 V)•Output

HD74LV123ADual Retriggerable Monostable MultivibratorsREJ03D0314–0600Z(Previous ADE-205-258D (Z))Rev.6.00Jun. 02, 2004 DescriptionThe HD74LV123A features output pulse-duration control by three methods. In the first method, the A input is low and the B input goes high. In the second method, the B input is high and the A input goes low. In the third method, the A input is low, the B input is high, and the clear (CLR) input goes high.The basic pulse duration is programmed by selecting external resistance and capacitance values.The external timing capacitor must be connected between Cext and Rext/Cext (positive) and an external resistor connected between Rext/Cext and VccTo obtain variable pulse durations, connect an external variable resistance between Rext/Cext and Vcc.Once triggered, the basic pulse duration can be extended by retriggering the gated low-level-active (A) or high-level-active (B) input. Pulse duration can be reduced by taking CLR low.Features•V CC = 2.0 V to 5.5 V operation•All inputs V IH (Max.) = 5.5 V (@V CC = 0 V to 5.5 V)•All outputs V O (Max.) = 5.5 V (@V CC = 0 V)•Output

HD74AC107/HD74ACT107Dual JK Flip-Flop (with Separate Clear and Clock)ADE-205-363 (Z)1st. EditionSep. 2000 DescriptionThe HD74AC107/HD74ACT107 dual JK master/slave flip-flops have a separate clock for each flip-flop. Inputs to the master section are controlled by the clock pulse. The clock pulse also regulates the state of the coupling transistors which connect the master and slave sections. The sequence of operation is as follows: 1) isolate slave from master; 2) enter information from J and K inputs to master; 3) disable J and K inputs;4) transfer information from master to slave.Features• Outputs Source/Sink 24 mA• HD74ACT107 has TTL-Compatible InputsPin ArrangementHD74AC107/HD74ACT1072Logic SymbolPin NamesJ 1, J 2, K 1, K 2Data InputsCP 1, CP 2Clock Pulse Inputs (Active Falling Edge)C D1, C D2Direct Clear Inputs (Active Low)Q 1, Q 2, Q 1, Q 2OutputsTruth TableInputs Outputs @ t n @ t n + 1J K Q L L Qn L H L H L H H HQ nH :High Voltage Level L :Low Voltage Levelt n :Bit time before clock pulse.t n + 1:Bit time after clock pulse.HD74AC107/HD74ACT1073Logic DiagramDC Characteristics (unless otherwise specified)ItemSymbol Max Unit ConditionMaximum quiescent supply current I CC 40µA V IN = V CC or ground, V CC = 5.5 V,Ta = Worst caseMaximum quiescent supply current I CC 4.0µA V IN = V CC or ground, V CC = 5.5 V,Ta = 25°CMaximum additional I CC /input (HD74ACT107)I CCT1.5mAV IN = V CC – 2.1 V, V CC = 5.5 V Ta = Worst caseHD74AC107/HD74ACT1074AC Characteristics: HD74AC107Ta = +25°C C L = 50 pFTa = –40°C to +85°C C L = 50 pF ItemSymbol V CC (V)*1Min Typ Max Min Max Unit Maximum clock f max3.3125——100—MHzfrequency 5.0150——125—Propagation delay t PLH 3.3 1.09.513.0 1.014.0ns C P to Q or Q 5.0 1.07.510.0 1.011.0Propagation delay t PHL 3.3 1.010.013.5 1.014.5ns C P to Q or Q 5.0 1.08.010.5 1.011.5Propagation delay t PLH 3.3 1.09.513.0 1.014.0ns C D to Q5.0 1.07.510.0 1.011.0Propagation delay t PHL 3.3 1.09.513.0 1.014.0ns C D to Q 5.01.07.510.01.011.0Note:1.Voltage Range 3.3 is 3.3 V ± 0.3 VVoltage Range 5.0 is 5.0 V ± 0.5 VOperating Requirements: HD74AC107Ta = +25°C C L = 50 pFTa = –40°C to +85°C C L = 50 pFItem Symbol V CC (V)*1Typ Guaranteed MinimumUnit Setup time t su3.3 3.0 5.5 6.0nsJ or k to C P 5.0 2.0 4.0 4.5Hold time t h3.3–1.50.00.0C P to J or k 5.0–0.50.00.0Pulse width t w 3.3 2.0 5.57.0C P or C D5.0 2.0 4.5 5.0Recovery time t rec 3.3 1.5 3.0 3.0C D to C P 5.01.03.03.0Note:1.Voltage Range 3.3 is 3.3 V ± 0.3 VVoltage Range 5.0 is 5.0 V ± 0.5 VHD74AC107/HD74ACT1075AC Characteristics: HD74ACT107Ta = +25°C C L = 50 pFTa = –40°C to +85°C C L = 50 pF ItemSymbol V CC (V)*1Min Typ Max Min Max Unit Maximum clock frequency f max 5.0100——80—MHz Propagation delay C P to Q or Q t PLH 5.0 1.09.512.5 1.013.5nsPropagation delay C P to Q or Q t PHL 5.0 1.010.513.0 1.014.0Propagation delay C D to Qt PLH 5.0 1.08.511.0 1.012.0Propagation delay C D to Q t PHL5.01.08.511.01.012.0Note:1.Voltage Range 5.0 is 5.0 V ± 0.5 VOperating Requirements: HD74ACT107Ta = +25°C C L = 50 pFTa = –40°C to +85°C C L = 50 pFItem Symbol V CC (V)*1Typ Guaranteed MinimumUnit Setup time J or k to C P t su 5.0 2.57.08.0nsHold time C P to J or k t h 5.00.0 1.5 1.5Pulse width C P or C Dt w 5.0 4.57.08.0Recovery time C D to C P t rec5.0—3.03.0Note:1.Voltage Range 5.0 is 5.0 V ± 0.5 VCapacitanceItemSymbol Typ Unit Condition Input capacitanceC IN 4.5pF V CC = 5.5 V Power dissipation capacitanceC PD35.0pFV CC = 5.0 VHD74AC107/HD74ACT107 Package Dimensions6HD74AC107/HD74ACT1077HD74AC107/HD74ACT1078Cautions1.Hitachi neither warrants nor grants licenses of any rights of Hitachi’s or any third party’s patent,copyright, trademark, or other intellectual property rights for information contained in this document.Hitachi bears no responsibility for problems that may arise with third party’s rights, includingintellectual property rights, in connection with use of the information contained in this document.2.Products and product specifications may be subject to change without notice.

HD74LVC16373A16-bit D-type Transparent Latches with 3-state OutputsADE-205-121B(Z)3rd EditionDecember 1996 DescriptionThe HD74LVC16373A has sixteen D type latches with three state outputs in a 48 pin package. When the latch enable input is high, the Q outputs will follow the D inputs. When the latch enable goes low, data at the D inputs will be retained at the outputs until latch enable returns high again. When a high logic level is applied to the output control input (1G, 2G), all outputs go to a high impedance state, regardless of what signals are present at the other inputs and the state of the storage elements. Low voltage and high speed operation is suitable at the battery drive product (note type personal computer) and low power consumption extends the life of a battery for long time operation.Features• V CC = 2.0 V to 5.5 V• All inputs V IH (Max.) = 5.5 V (@V CC = 0 V to 5.5 V)• All outputs V OUT (Max.) = 5.5 V (@V CC = 0 V or output off state)• Typical V OL ground bounce < 0.8 V (@V CC = 3.3 V, Ta = 25°C)• Typical V OH undershoot > 2.0 V (@V CC = 3.3 V, Ta = 25°C)• High output current ±24 mA (@V CC = 3.0 V to 5.5 V)Function TableInputsG LE D Output QH X X ZL H L LL H H HL L X QlevelH: HighL:Low levelX:ImmaterialZ:High impedanceQ:Level of Q before the indicated steady input conditions were established.HD74LVC16373A Pin Arrangement2HD74LVC16373A3Absolute Maximum RatingsItemSymbol Ratings Unit ConditionsSupply voltage V CC –0.5 to 6.0V Input diode current I IK –50mA V I = –0.5 V Input voltage V I –0.5 to 6.0V Output diode current I OK –50mA V O = –0.5 V 50mA V O = V CC +0.5 V Output voltage V O –0.5 to V CC +0.5V Output "H" or "L"–0.5 to 6.0V Output "Z" or V CC :OFF Output current I O±50mA V CC , GND current / pin I CC or I GND 100mA Storage temperatureTstg–65 to +150°CNote:The absolute maximum ratings are values which must not individually be exceeded, and furthermore,no two of which may be realized at the same time.Recommended Operating ConditonsItemSymbol Ratings Unit Conditions Supply voltage V CC 1.5 to 5.5V Data hold 2.0 to 5.5V At operation Input / output voltageV I 0 to 5.5V G , LE, D V O0 to V CC V Output "H" or "L"0 to 5.5V Output "Z" or V CC :OFFOperating temperature Ta –40 to 85°C Output currentI OH –12mA V CC = 2.7 V –24*2mA V CC = 3.0 V to 5.5 V I OL12mA V CC = 2.7 V 24*2mA V CC = 3.0 V to 5.5 V Input rise / fall time *1t r , t f10ns/VNotes: 1.This item guarantees maximum limit when one input switches.Waveform : Refer to test circuit of switching characteristics.2.duty cycle ≤ 50%HD74LVC16373A4Electrical CharacteristicsTa = –40 to 85°CItem Symbol V CC (V)Min Max Unit Test Conditions Input voltageV IH 2.7 to 3.6 2.0—V 4.5 to 5.5V CC ×0.7—V V IL2.7 to3.6—0.8V4.5 to5.5—V CC ×0.3V Output voltageV OH2.7 to 5.5V CC –0.2—V I OH = –100 µA 2.7 2.2—V I OH = –12 mA3.0 2.4—V 3.0 2.2—V I OH = –24 mA4.53.8—V V OL2.7 to 5.5—0.2V I OL = 100 µA 2.7—0.4V I OL = 12 mA3.0—0.55V I OL = 24 mA4.5—0.55V Input currentI IN 0 to 5.5—±5.0µA V IN = 5.5 V or GND Off state output current I OZ 2.7 to 5.5—±5.0µA V IN = V CC , GNDV OUT = 5.5 V or GND Output leak currentI OFF0—20µA V IN / V OUT = 5.5 V Quiescent supply current I CC2.7 to3.6—±20µA V IN / V OUT = 3.6 to 5.5 V 2.7 to 5.5—20µA V IN = V CC or GND∆I CC3.0 to 3.6—500µAV IN = one input at(V CC –0.6)V,other inputs at V CC or GNDHD74LVC16373A5Switching CharacteristicsTa = –40 to 85°CItemSymbol V CC (V)Min Typ Max Unit From (Input)To (Output)Propagation delay timet PLH 2.7——7.7ns DQt PHL 3.3±0.3 1.5—7.0ns 5.0±0.5—— 5.5ns t PLH 2.7——8.0ns LEQt PHL3.3±0.3 2.0—7.0ns 5.0±0.5—— 5.5ns Output enable timet ZH 2.7——8.0ns GQt ZL3.3±0.3 1.5—7.0ns 5.0±0.5—— 6.0ns Output disable timet HZ 2.7——8.0ns GQt LZ3.3±0.3 1.5—7.0ns 5.0±0.5—— 6.0ns Setup timet su2.7 2.0——ns3.3±0.3 2.0——ns 5.0±0.52.0——ns Hold timet h2.7 1.5——ns3.3±0.3 1.5——ns 5.0±0.51.5——ns Pulse widtht w2.73.0——ns 3.3±0.3 3.0——ns 5.0±0.53.0——ns Between output pins skew *1t OSLH 2.7———ns t OSHL3.3±0.3—— 1.0ns 5.0±0.5—— 1.0ns Input capacitance C IN 2.7— 3.0—pF Output capacitance C O2.7—15.0—pFNote:1.This parameter is characterized but not tested.tos LH = | t PLHm – t PLHn |, tos HL = | t PHLm – t PHLn |HD74LVC16373A Test CircuitWaveforms – 16HD74LVC16373A Waveforms – 2Waveforms – 37HD74LVC16373A Waveforms – 48Hitachi CodeJEDECEIAJWeight (reference value)TTP-48DB——0.20 gUnit: mm*Dimension including the plating thickness Base material dimensionCautions1.Hitachi neither warrants nor grants licenses of any rights of Hitachi’s or any third party’s patent,copyright, trademark, or other intellectual property rights for information contained in this document.Hitachi bears no responsibility for problems that may arise with third party’s rights, includingintellectual property rights, in connection with use of the information contained in this document.2.Products and product specifications may be subject to change without notice.
