DESCRIPTION

The AC240 is an advanced CMOS OCTAL BUS

BUFFER (3-STATE) fabricated with sub-micron

silicon gate and double-layer metal wiring C

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 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.
