DESCRIPTION
The AC14 is an advanced high-speed CMOS
HEX INVERTER fabricated with sub-micron
silicon gate and double-layer metal wiring C
2
MOS
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.
