M74HC14 is a high speed CMOS hex SCHMITT INVERTER fabricated with silicon gate C2MOS technology. Pin configuration and function are the same as those of the M74HC04 but all inputs have 20% Vcc hysteresis level. This, together with its schmitt trigger function, allows it to be used on line receivers with slow rise/fall input signals. All inputs are equipped with protection circuits against static discharge and transient excess voltage.
The M74HC14 is a high‑speed CMOS hex Schmitt‑trigger inverter fabricated with silicon‑gate CMOS technology. All inputs feature protection against static discharge and transient over‑voltage, and the device offers a wide operating voltage range of 2 V to 6 V.
