DescriptionThe M74HC14 is a high speed CMOS hex Schmitt inverter fabricated with silicon gate C2MOS technology. Pin configuration and functions are the same as those of the M74HC04 but all the inputs have 20% VCC hysteresis level.This, together with its Schmitt trigger function, allows the device 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.
