SL74HC14
Hex Schmitt-Trigger Inverter
High-Performance Silicon-Gate CMOS
The SL74HC14 is identical in pinout to the LS/ALS14, LS/ALS04. The
device inputs are compatible with standard CMOS outputs; with pullup
resistors, they are compatible with LS/ALSTTL outputs.
The SL74HC14 is useful to “square up” slow input rise and fall times.
Due to the hysteresis voltage of the Schmitt trigger, the SL74HC14A
finds applications in noisy environments.
