DESCRIPTION
The ACT14 is an advanced high-speed CMOS
HEX SCHMITT INVERTER fabricated with
sub-micron silicon gate and double-layer metal
wiring C2MOS 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.
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 isdefined as the value of the IC’sinternal equivalent capacitance which is calculated fromthe operating current consumption without load. (Referto
Test Circuit).Average operating current can be obtained by the following equation. ICC(opr) = CPD • VCC • fIN + ICC/6 (per circuit)
