DESCRIPTION

The ACT125 is an high-speed CMOS QUAD BUS

BUFFERS fabricated with sub-micron silicon gate

and

double-layer

metal

wiring

C

technology. It is ideal for low power applications

maintaining high speed operation similar to

equivalent Bipolar Schottky TTL.

These devices require the same 3-STATE control

input G to be taken high to make the output go in

to the 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.
