HD74LVC2244AOctal Buffers / Line Drivers with 3–state OutputsADE-205-234 (Z)Preliminary1st. EditionDecember 1998 DescriptionThe HD74LVC2244A has eight line drivers with three state outputs in a 20 pin package. This device is a noninverting buffer and has two active low enables (1G and 2G). Each enable independently controls four buffers.All outputs, which are designed to sink up to 12 mA, include equivalent 26 Ω resistors to reduce overshoot and undreshoot.is between 0 and 1.5 V, the device is in the high impedance state during power up or power When VCCdown.Low voltage and high speed operation is suitable at battery drive product (note type personal computer) and low power consumption extends the life of a battery for long time operation.Features• V CC = 1.65 to 5.5 V• All inputs V IH (Max) = 5.5 V (@V CC = 0 to 5.5 V)• All outputs V O (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 ±12 mA (@V CC = 3.0 to 5.5 V)• All outputs have equivalent 26 Ω series resistors, so no external resistors are requiredHD74LVC2244AFunction TableInputs Output YG AH X ZL H HL L LH : High levelL : Low levelX : ImmaterialZ : High impedancePin Arrangement2HD74LVC2244A3Absolute Maximum RatingsItemSymbol Ratings Unit ConditionsSupply voltage V CC –0.5 to 7.0V Input voltage V I –0.5 to 7.0V Output voltage V O –0.5 to 7.0VOutput “Z” or V CC : OFF –0.5 to V CC +0.5Output “H” or “L”Input diode current I IK –50mA V I < 0Output diode current I OK –50mA V O < 0Output current I O±50mA V CC , GND current I CC or I GND ±100mA Storage temperatureTstg–65 to 150°C Note:The absolute maximum ratings are values which must not individually be exceeded, and furthermoreno two of which may be realized at the same time.Recommended Operating ConditionsItemSymbol Ratings Unit Conditions Supply voltage V CC 1.65 to 5.5VAt operation 1.5 to 5.5Data retention onlyInput voltage V I 0 to 5.5V Output voltage V O 0 to 5.5VOutput “Z” or V CC : OFF 0 to V CC Output “H” or “L”Output currentI OH–2mA V CC = 1.65 V –4V CC = 2.3 V –8V CC = 2.7 V –12V CC = 3.0 to 5.5 V I OL2V CC = 1.65 V 4V CC = 2.3 V 8V CC = 2.7 V 12V CC = 3.0 to 5.5 VInput rise / fall time t r , t f 0 to 6ns / V Operating temperatureTa–40 to +85°CHD74LVC2244A Logic Diagram4HD74LVC2244A5Electrical Characteristics (Ta = –40 to 85°C)Item Symbol V CC (V)Min Typ Max Unit Test Conditions Input voltageV IH1.65 to 1.95V CC ×0.65——V2.3 to 2.7 1.7——2.7 to3.6 2.0——4.5 to 5.5V CC ×0.7——V IL1.65 to 1.95——V CC ×0.352.3 to 2.7——0.72.7 to3.6——0.84.5 to5.5——V CC ×0.3Output voltageV OH1.65 to 5.5V CC –0.2——VI OH = –100 µA 1.65 1.2——I OH = –2 mA 2.3 1.7——I OH = –4 mA2.7 2.2——3.0 2.4——I OH = –6 mA 2.7 2.0——I OH = –8 mA 3.0 2.0——I OH = –12 mA4.53.6——V OL1.65 to 5.5——0.2I OL = 100 µA 1.65——0.45I OL = 2 mA 2.3——0.7I OL = 4 mA 2.7——0.43.0——0.55I OL = 6 mA 2.7——0.6I OL = 8 mA 3.0——0.8I OL = 12 mA 4.5——0.8Input current I IN 0 to 5.5——±5µA V IN = 0 to 5.5 V Off state output current I OZ1.65 to 5.5——±5µA V OUT = 0 to 5.5 V Output leak current I OFF 0——±5µA V IN or V O = 5.5 VQuiescent supply I CC1.65 to 3.6——10µA V IN = 3.6 to 5.5 V *1, I O = 0current1.65 to 5.5——10V IN = V CC or GND∆I CC 2.7 to 3.6——500V IN = one input at (V CC –0.6)V,other inputs at V CC or GND Input capacitance C IN 3.3—TBD —pF V IN = V CC or GND Output capacitance C O3.3—TBD—pFV OUT = V CC or GND Note:1.This applies in the disabled state only.HD74LVC2244A6Switching Characteristics (Ta = –40 to 85°C)ItemSymbol V CC (V)MinTyp Max Unit FROM (Input)TO(Output)Propagation delay timet PLH 1.8±0.15TBD TBD TBD nsAYt PHL2.5±0.2TBD TBD TBD 2.7—— 6.43.3±0.3 1.5— 5.55.0±0.5—— 4.1Output enable timet ZH 1.8±0.15TBD TBD TBD nsGYt ZL2.5±0.2TBD TBD TBD 2.7——8.13.3±0.3 1.0—7.15.0±0.5—— 5.6Output disable timet HZ 1.8±0.15TBD TBD TBD nsGYt LZ2.5±0.2TBD TBD TBD 2.7——7.33.3±0.3 1.5— 6.85.0±0.5—— 5.7Between output pin skew *1t OSLH1.8±0.15TBD TBD TBD ns t OSHL2.5±0.2TBD TBD TBD 2.7———3.3±0.3—— 1.05.0±0.5——1.0Note : 1.This parameter is characterized but not tested.t OSLH = |t PLHm –t PLHn |, t OSHL = |t PHLm –t PHLn |HD74LVC2244A7Test Circuit(V CC = 1.8±0.15 V, V CC = 2.5±0.2 V)HD74LVC2244A8(V CC = 2.7 V, V CC = 3.3±0.3 V, V CC = 5.0±0.5 V)HD74LVC2244A9(V CC = 1.8±0.15 V, V CC = 2.5±0.2 V)HD74LVC2244A10(V CC = 2.7 V, V CC = 3.3±0.3 V, V CC = 5.0±0.5 V)HD74LVC2244A Package DimensionsUnit : mm11HD74LVC2244A12Hitachi Code JEDEC EIAJWeight (reference value)TTP-20DA ——0.07 gUnit: mm*Dimension including the plating thicknessBase material dimension元器件交易网Cautions1.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.
