SEMICONDUCTOR TECHNICAL DATA
Hex Schmitt-Trigger Inverter
High–Performance Silicon–Gate CMOS
The MC54/74HC14A is identical in pinout to the LS14, LS04 and the
HC04. The device inputs are compatible with Standard CMOS outputs;
with pullup resistors, they are compatible with LSTTL outputs.
The HC14A is useful to “square up” slow input rise and fall times. Due
to hysteresis voltage of the Schmitt trigger, the HC14A finds applications
in noisy environments.
