HD74LVC2244A

·  V_CC = 2.7 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 ±24 mA (@VCC = 3.0 to 5.5 V)
·  All outputs have equivalent 26 W series resistors, so no external resistors are required

The HD74LVCZ244A has eight line drivers with three state outputs in a 20 pin package. This  HD74LVCZ244A is a noninverting buffer and has two active low enables (1G and 2G). Each enable independently controls four buffers.When V_CC is between 0 and 1.5 V, the device is in the high impedance state during power up or power down.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.
