Overview
The 74HCT14PW/C4118 is a hex inverter with Schmitt-trigger inputs, manufactured by NXP USA Inc. This device is part of the 74HCT series and is designed to interface with TTL logic levels. It features reduced input threshold levels and includes clamp diodes, allowing the use of current limiting resistors to interface inputs to voltages in excess of VCC. The Schmitt trigger inputs transform slowly changing input signals into sharply defined, jitter-free output signals.
