MC74HCT14A

Hex Schmitt-Trigger

Inverter with LSTTL

Compatible Inputs

High−Performance Silicon−Gate CMOS

The MC74HCT14A may be used as a level converter for interfacing

TTL or NMOS outputs to high−speed CMOS inputs.

The HCT14A is useful to “square up” slow input rise and fall times.

Due to the hysteresis voltage of the Schmitt trigger, the HCT14A finds

applications in noisy environments.
