The 74ACT14 is an advanced high-speed CMOS
HEX SCHMITT INVERTER fabricated with
sub-micron silicon gate and double-layer metal
wiring C
2
MOS tecnology.
The internal circuit is composed of 3 stages
including buffer output , which enables high noise
immunity and stable output.
The device is designed to interface directly High
Speed CMOS systems with TTL, NMOS and
TSSOPDIPSOP

CMOS output voltage levels.
This together with its schmitt trigger function
allows it to be used on line receivers with slow
rise/fall input signals.
All inputs and outputs are equipped w ith protection circuits a gainst static discharge, giving them
2KV ESD immunity and transient excess voltage.
