IN74ACT14

HEX SCHMITT-TRIGGER INVERTER

High-Speed Silicon-Gate CMOS

The IN74ACT14 is identical in pinout to the LS/ALS14,

HC/HCT14. The IN74ACT14 may be used as a level converter

for interfacing TTL or NMOS outputs to High Speed CMOS

inputs.

The IN74ACT14 is useful to “square up” slow input rise and

fall times. Due to the hysteresis voltage of the Schmitt trigger, the

IN74ACT14 finds applications in noisy environments.

• TTL/NMOS Compatible Input Levels

• Outputs Directly Interface to CMOS, NMOS, and TTL

• Operating Voltage Range: 4.5 to 5.5 V

• Low Input Current: 1.0 µA; 0.1 µA @ 25°C

• Outputs Source/Sink 24 mA
