Description	Octal Buffers/Line Drivers/Line Receivers(with noninverted 3-state outputs)
Datasheet	HD74HC244_HitachiSemiconductor.pdf

The HD74HC244 is a non-inverting buffer and has two active low enables (1G and 2G ).

Each enable independently controls 4 buffers.

This device does not have schmitt trigger inputs.

High Speed Operation: tpd = 11 ns typ (CL = 50 pF) High Output Current: Fanout of 15 LSTTL Loads Wide Operating Voltage: VCC = 2 to 6 V Low Input Current: 1 µA max Low Quiescent Supply Current: ICC (static) = 4 µA max (Ta = 25°C) Function Table Inputs G H L L A X H L Output Y Z H L Notes H: high level L: low level X: irrelevant Z: off (high-impedance) state of a 3-state output HD74HC244 Pin Arrangement 1G1 1A1 2Y4 1A2 2Y3 1A3 2Y2 1A4 2Y1 1 2.
