DESCRIPTION

The ACT240 is an advanced CMOS OCTAL BUS

BUFFER (3-STATE) fabricated with sub-micron

silicon gate and double-layer metal wiring C2MOS

technology. It is ideal for low power applications

mantaining high speed operation similar to

equivalent Bipolar Schottky TTL.

G control output governs four BUS BUFFERs.

This device is desibned to be used with 3 state

memory address drivers, etc.

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.
