The M74HCT14 is designed to directly interface 2 Pin configuration and function are the same as HSCMOS systems with TTL and NMOS those of the M74HCT04 but all inputs have 0.7 V components. hysteresis level. This together with its schmitt All inputs are equipped with protection circuits trigger function allows it to be used on line receiver against static discharge and transient excess with slow rise/fall input signals. voltage.
