Overview
The 74HCT14D/AUJ, produced by Nexperia (formerly part of NXP USA Inc.), is a hex inverter with Schmitt-trigger inputs. This device is designed to interface with TTL logic levels, making it versatile for various electronic designs. 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.
