Overview
The SN74LS14NSR is a hex inverter Schmitt trigger integrated circuit produced by Texas Instruments. This device contains six independent Schmitt-trigger inverters, each performing the Boolean function Y = A in positive logic. The Schmitt-trigger inputs are designed to provide high noise immunity and can operate from very slow transition edge inputs, making them suitable for a variety of applications where noisy or slow inputs are present.
