Overview
The SN74AHCT14D is a hex Schmitt-trigger inverter integrated circuit produced by Texas Instruments. This device contains six independent inverters, each performing the Boolean function Y = A in positive logic. The Schmitt-trigger inputs make it suitable for handling noisy or slow input signals, preventing oscillations and ensuring stable output.
