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. Outputs Directly Interface to
CMOS, NMOS, and TTL Operating
