DESCRIPTION

The 74ACT244 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

The device is designed to interface directly High

Speed CMOS systems with TTL, NMOS and

CMOS output voltage levels.

All inputs and outputs are equipped with

protection circuits against static discharge, giving

them 2KV ESD immunity and transient excess

voltage.
