74LS14 Datasheet – Hex Inverter with Schmitt Trigger

Part Number : 74LS14, DM74LS14N, HD74LS14P

Function : Hex Inverter with Schmitt Trigger Input

Package :  DIP 14 Pin Type

Manufacturers : Fairchild, Hitachi, TI


74LS14 Hex Inverter

Description :

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.
