74AHCT14A

Hex inverting Schmitt trigger

The 74AHCT14A is a hex inverter with Schmitt-trigger inputs, capable of transforming slowly changing input signals into sharply defined, jitter-free output signals.

Designed to operate over a V_CC range from 4.5 V to 5.5 V, the inputs are TTL compatible. This range allows the device to be used to translate from 3.3 V to 5 V.

This device is fully specified for partial Power-down applications using I_OFF. The I_OFF circuitry disables the output, preventing the damaging backflow current through the device when it is powered down.
