MOTOROLA
SEMICONDUCTOR TECHNICAL DATA
Hex Schmitt-Trigger Inverter
with LSTTL Compatible Inputs
High–Performance Silicon–Gate CMOS
The MC54/74HCT14A may be used as a level converter for interfacing
TTL or NMOS outputs to high–speed CMOS inputs.
The HCT14A is identical in pinout to the LS14.
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.
