74HC138中文资料74H C138是一款高速C MOS器件，74H C138引脚兼容低功耗肖特基TTL（LS TTL）系列。

74HC138译码器可接受3位二进制加权地址输入（A0, A1和A3），并当使能时，提供8个互斥的低有效输出（Y0至Y7）。

74H C138特有3个使能输入端：两个低有效（E1和E2）和一个高有效（E3）。

除非E1和E2置低且E3置高，否则74H C138将保持所有输出为高。

利用这种复合使能特性，仅需4片74H C138芯片和1个反相器，即可轻松实现并行扩展，组合成为一个1-32（5线到32线）译码器。

任选一个低有效使能输入端作为数据输入，而把其余的使能输入端作为选通端，则74H C138亦可充当一个8输出多路分配器，未使用的使能输入端必须保持绑定在各自合适的高有效或低有效状态。

74H C138与74H C238逻辑功能一致，只不过74HC138为反相输出74HC138功能:CD74HC138 ，CD74HC238和CD74HCT138 ，CD74HCT238是高速硅栅CMOS解码器，适合内存地址解码或数据路由应用。

74HC138 作用原理于高性能的存贮译码或要求传输延迟时间短的数据传输系统,在高性能存贮器系统中,用这种译码器可以提高译码系统的效率。

将快速赋能电路用于高速存贮器时,译码器的延迟时间和存贮器的赋能时间通常小于存贮器的典型存取时间,这就是说由肖特基钳位的系统译码器所引起的有效系统延迟可以忽略不计。

HC138 按照三位二进制输入码和赋能输入条件,从8 个输出端中译出一个低电平输出。

两个低电平有效的赋能输入端和一个高电平有效的赋能输入端减少了扩展所需要的外接门或倒相器,扩展成24 线译码器不需外接门;扩展成32 线译码器,只需要接一个外接倒相器。

在解调器应用中,赋能输入端可用作数据输入端。

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.

When LE is taken low, the Q outputs will be latched precisely at the logic level of D input data.While the OE input is at low level, the eight outputs will be in a normal logic state (high or low logic level) and while is at high level the outputs will be in a high impedance state.The 3-State output configuration and the wide choice of outline make bus organized system simple.All inputs are equipped with protection circuits against static discharge and transient excess voltage.M74HC573OCTAL D-TYPE LATCHWITH 3 STATE OUTPUT NON INVERTINGPIN CONNECTION AND IEC LOGIC SYMBOLSORDER CODESPACKAGE TUBE T & RDIP M74HC573B1R SOP M74HC573M1RM74HC573RM13TR TSSOPM74HC573TTRM74HC5732/12INPUT AND OUTPUT EQUIVALENT CIRCUITPIN DESCRIPTIONTRUTH TABLEX: Don’t CareZ: High Impedance(*): Q Outputs are latched at the time when the LE input is taken low logic level.LOGIC DIAGRAMPIN No SYMBOL NAME AND FUNCTION 1OE 3 State Output Enable Input (Active LOW)2, 3, 4, 5, 6, 7, 8, 9D0 to D7Data Inputs12, 13, 14, 15, 16, 17, 18, 19Q0 to Q73 State Latch Outputs11LE Latch Enable Input 10GND Ground (0V)20V CCPositive Supply VoltageINPUTSOUTPUTSOE LE D QH X X ZL L X NO CHANGE (*)L H L L LHHHM74HC5733/12ABSOLUTE MAXIMUM RATINGSAbsolute Maximum Ratings are those values beyond which damage to the device may occur.

(Refer to Test Circuit). Average operating current can be obtained by the following equation. I CC(opr) = C PD x V CC x f IN + I CC /8 (per Flip Flop) and the C PD when n pcs of Flip Flop operate, can be gained by the following equation: C PD(TOTAL) = 33 + 18 x n (pF)TEST CIRCUITC L = 50pF/150pF or equivalent (includes jig and probe capacitance)R 1 = 1K Ω or equivalentR T = Z OUT of pulse generator (typically 50Ω)SymbolParameterTest ConditionValue UnitV CC (V)T A = 25°C -40 to 85°C -55 to 125°C Min.Typ.Max.Min.Max.Min.Max.C IN Input Capacitance 5101010pF C OUT OutputCapacitance10pF C PDPower Dissipation Capacitance (note 1)51pF TESTSWITCH t PLH , t PHL Open t PZL , t PLZ V CC t PZH , t PHZGNDM74HC5737/12WAVEFORM 1: LE TO Qn PROPAGATION DELAYS, LE MINIMUM PULSE WIDTH, Dn TO LE SETUP AND HOLD TIMES (f=1MHz; 50% duty cycle)WAVEFORM 2: OUTPUT ENABLE AND DISABLE TIMES(f=1MHz; 50% duty cycle)M74HC5738/12WAVEFORM 3: PROPAGATION DELAY TIMES(f=1MHz; 50% duty cycle)M74HC573Information furnished is believed to be accurate and reliable.

74HC573N，8路D 型锁存器，具有三态输出74HC573N型号标识及主要参数：74HC573N封装信息：类型：DIP引脚：20宽度：300 mil74HC573N包装规格：类型：Tube（管装）每管：18 pcs74HC573 概述74HC573是一款高速CMOS器件，74HC573引脚兼容低功耗肖特基TTL（LSTTL）系列。

74HC573包含八路D 型透明锁存器，每个锁存器具有独立的D 型输入，以及适用于面向总线的应用的三态输出。

所有锁存器共用一个锁存使能（LE）端和一个输出使能（OE）端。

当LE为高时，数据从Dn输入到锁存器，在此条件下，锁存器进入透明模式，也就是说，锁存器的输出状态将会随着对应的D输入每次的变化而改变。

当LE为低时，锁存器将存储D输入上的信息一段就绪时间，直到LE的下降沿来临。

当OE为低时，8个锁存器的内容可被正常输出；当OE为高时，输出进入高阻态。

OE端的操作不会影响锁存器的状态。

These inputs are valid for slow rising/falling signals, (tr=tf=l sec).The device may also be triggered by using the CLR input (positive-edge) because of the Schmitt-trigger input; after triggering the output maintains the MONOSTABLE state for the time period determined by the external resistor Rx and capacitor Cx. When Cx > 10nF and Rx > 10K Ω,the output pulse width value is approsimatively given by the formula : tW(OUT) = K · Cx · Rx.(K ≅ 0.45).Taking CLR low breaks this MONOSTABLE STATE. If the next trigger pulse occurs during the MONOSTABLE period it makes the MONOSTABLE period longer. Limit for values of Cx and Rx : Cx : NO LIMIT Rx : V cc < 3.0V 5K Ω to 1M Ω V cc > 3.0V 1K Ω to 1M ΩAll inputs are equipped with protection circuits against static discharge and transient excess voltage.M74HC123DUAL RETRIGGERABLE MONOSTABLE MULTIVIBRATORPIN CONNECTION AND IEC LOGIC SYMBOLSORDER CODESPACKAGE TUBE T & RDIP M74HC123B1R SOP M74HC123M1RM74HC123RM13TR TSSOPM74HC123TTRM74HC1232/12INPUT AND OUTPUT EQUIVALENT CIRCUITPIN DESCRIPTIONTRUTH TABLEPIN No SYMBOL NAME AND FUNCTION 1,91A, 2A Trigger Inputs (Negative Edge Triggered)2, 101B, 2B Trigger Inputs (Positive Edge Triggered)3, 11 1 CLR 2 CLR Direct Reset LOW and trigger Action at Positive Edge4, 121Q, 2Q Outputs (Active Low)72R X /C X External ResistorCapacitor Connection 13, 51Q, 2Q Outputs (Active High)14, 6 1C X 2C X External Capacitor Connection151R X /C X External ResistorCapacitor Connection 8GND Ground (0V)16VccPositive Supply VoltageM74HC123 SYSTEM DIAGRAMThis logic diagram has not be used to estimate propagation delaysTIMING CHART3/12M74HC1234/12BLOCK DIAGRAM(2) Dx is a clamping diode.The external capacitor is charged to Vcc in the stand-by-state, i.e. no trigger. When the supply voltage is turned off Cx is di scharged mainly trough an internal parasitic diode(see figures). If Cx is sufficiently large and Vcc decreases rapidly, there will be some possibility of damaging the I.C. with a surge current or latch-up. If the voltage supply filter capacitor is large enough and Vcc decrease slowly, the surge current is automatically limited and damage to the I.C. is avoided. The maximum forward current of the parasitic diode is approximately 20 mA. In cases where Cx is large the time taken for the supply voltage to fall to 0.4 Vcc can be calculated as follows : t f > (Vcc - 0.7) x Cx/20mAIn cases where t f is too short an external clamping diode is required to protect the I.C. from the surge current.FUNCTIONAL DESCRIPTION STAND-BY STATEThe external capacitor,Cx, is fully charged to Vcc in the stand-by state. Hence, before triggering,transistor Qp and Qn (connected to the Rx/Cx node) are both turned-off. The two comparators that control the timing and the two reference voltage sources stop operating. The total supply current is therefore only leakage current.TRIGGER OPERATION Triggering occurs when :1 st) A is "LOW" and B has a falling edge;2 nd) B is "HIGH" and A has a rising edge;3 rd) A is "LOW" and B is HIGH and C1 has a rising edge;After the multivibrator has been retriggered comparator C1 and C2 start 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 reset the flip-flop and Qn is turned off.At this point C1 stops functioning but C2 continues 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 remains high until the voltage at R/C external rises again to V REFH . At this point C2output goes low and O goes low. C2 stop operating. That means that after triggering when the voltage R/C external returns 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 capacitor and the delay time in the I.C. can be ignored, the width of the output pulse tw (out) is as follows :tW(OUT) = 0.45 Cx · RxRE - TRIGGERED OPERATIONWhen a second trigger pulse follows the first its effect will depend on the state of the multivibrator.If the capacitor Cx is being charged the voltage level of R/C external falls to V REFL 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 minimum time for a second trigger to be effective depends on Vcc and Cx RESET OPERATIONCL is normally high. If CL is low, the trigger is not effective because Q output goes low and trigger control flip-flop is reset.Also transistor Op is turned on and Cx is charged quickly to Vcc. This means if CL input goes low the IC becomes waiting state both in operating and non operating state.M74HC1235/12ABSOLUTE MAXIMUM RATINGSAbsolute Maximum Ratings are those values beyond which damage to the device may occur.

74hc573中文资料参数
特点：
·三态总线驱动输出
·置数全并行存取
·缓冲控制输入
·使能输入有改善抗扰度的滞后作用
原理说明：
M54HC563/74HC563/M54HC573/74HC573的八个锁存器都是透明的D 型锁存器，当使能（G）为高时，Q 输出
将随数据（D）输入而变。

当使能为低时，输出将锁存在已建立的数据电平上。

输出控制不影响锁存器的内部工作，即老数据可以保持，甚至当输出被关闭时，
新的数据也可以置入。

这种电路可以驱动大电容或低阻抗负载，可以直接与系统总线接口并驱动总线，而不需要外接口。

特别适用于缓冲寄存器，I/O 通道，双向总线驱动器和工作寄存器。
