KK74LS14D

TECHNICAL DATA KK74LS14 Hex Schmitt-Trigger Inverter This device contains six independent gates each of which performs the logic INVERT function. Each input has hysteresis which increases the noise immunity and transforms a slowly changing input signal to a fast changing, jitter free output.
