DESCRIPTION

The 74AC244 is an advanced high-speed CMOS

OCTAL BUS BUFFER (3-STATE) fabricated with

sub-micron silicon gate and double-layer metal

wiring C2MOS tecnology.

The G input controls four BUS BUFFERs.

This device is designed to be used with 3 state

memory address drivers, etc.

All

inputs

and

outputs

are

equipped

with

protection circuits against static discharge, giving

them 2KV ESD immunity and transient excess

voltage.
