TECHNICAL DATA
KK74HC14A
Hex Schmitt-Trigger Inverter
The KK74HC14A is identical in pinout to the LS/ALS14. The device
inputs are compatible with standard CMOS outputs; with pullup resistors,
they are compatible with LS/ALSTTL outputs.
The KK74HC14A is useful to 鈥渟quare up鈥?slow input rise and fall times.
Due to the hysteresis voltage of the Schmitt trigger, the KK74HC14A finds
applications in noisy environments.
