Datasheet 74HC14, 74HCT14 (Nexperia)

74HC14; 74HCT14 Hex inverting Schmitt trigger Rev. 10 — 29 February 2024 Product data sheet 1. General description
The 74HC14; 74HCT14 is a hex inverter with Schmitt-trigger inputs. This device features reduced input threshold levels to allow interfacing to TTL logic levels. Inputs also include clamp diodes, this enables the use of current limiting resistors to interface inputs to voltages in excess of VCC. Schmitt trigger inputs transform slowly changing input signals into sharply defined jitter-free output signals.
