Overview
The SN7414N is a hex Schmitt-Trigger inverter integrated circuit produced by Texas Instruments. This device contains six independent inverters, each functioning as a Schmitt-Trigger inverter. The Schmitt-Trigger action provides different input threshold levels for positive-going and negative-going signals, which enhances noise immunity and prevents oscillations from slow or noisy input signals. The SN7414N is temperature compensated, ensuring clean and jitter-free output signals even from the slowest of input ramps.
