7414 - Hex Schmitt-Trigger Inverter

The 7414 is a hex Schmitt-trigger inverter IC in the 7400 series of TTL logic devices. It contains six independent inverters with Schmitt-trigger inputs, which provide hysteresis for noise immunity and fast switching. This makes it ideal for waveform shaping, signal conditioning, and debouncing noisy inputs. Operating at 5V, the 7414 is commonly used in digital circuits requiring stable logic transitions.
