DESCRIPTION

The AC14 is an advanced high-speed CMOS

HEX INVERTER

fabricated with sub-micron

silicon gate and double-layer metal wiring C

2MOS

technology. It is ideal for low power applications

mantaining high speed operation similar to

equivalent Bipolar Shottky TTL.

The internal circuit is composed of 3 stages

including buffer output, which enables high noise

immunity and stable output.

This together with its schmitt trigger function

allows it to be used on line receivers with slow

rise/fall input segnals.

All

inputs and

outputs

are

equipped with

protection circuits against static discharge, giving

them 2KV ESD immunity and transient excess

voltage.
