DESCRIPTION
The 74ACT14 is an advanced high-speed CMOS
HEX SCHMITT INVERTER fabricated with
sub-micron silicon gate and double-layer metal
wiring C2MOS 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

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 with protection circuits against static discharge, giving them
2KV ESD immunity and transient excess voltage.

1) CPD is defined as the value of the IC’s internal equivalent capacitance which is calculated from the operating current consumption without
load. (Refer to Test Circuit). Average operating current can be obtained by the following equation. ICC(opr) = CPD x VCC x fIN + ICC/6 (per gate)
