High-Performance Silicon-Gate CMOS
The IN74HCT14A may be used as a level converter for
interfacing TTL or NMOS outputs to high-speed CMOS inputs.
The IN74HCT14A is identical in pinout to the LS/ALS14.
The IN74HCT14A is useful to “square up” slow input rise and
fall times. Due to the hysteresis voltage of the Schmitt trigger, the
IN74HCT14A finds applications in noisy environments.
TTL/NMOS-Compatible Input Levels.
Outputs Directly Inferface to CMOS, NMOS and TTL.
Operating Voltage Range: 4.5 to 5.5 V
Low Input Current: 1.0
