description

These Schmitt-trigger devices contain six independent inverters. They perform the Boolean function Y = A\. Because of the Schmitt action, they have different input threshold levels for positive-going (V_T+) and for negative-going (V_T-) signals.

These circuits are temperature compensated and can be triggered from the slowest of input ramps and still give clean, jitter-free output signals. They also have a greater noise margin than conventional inverters.

SN54ACT14 is characterized for operation over the full military temperature range of -55°C
to 125°C. The SN74ACT14 is characterized for operation from -40°C to 85°C.
