DESCRIPTION

The 74ACT125 is an advanced high-speed CMOS

QUAD BUS BUFFER fabricated with sub-micron

technology.

This device require the 3-STATE control input G to

be set high to place the output in high impedance

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.
