74HC14D Hex Inverting Schmitt Trigger IC - SOIC-14 Package is a CMOS hex inverter IC featuring six independent inverting gates with Schmitt-trigger inputs. The Schmitt-trigger inputs provide hysteresis, allowing slowly changing or noisy input signals to be converted into clean digital output signals. It supports a wide 2 V to 6 V supply range and is suitable for waveform shaping, signal conditioning, oscillators, switch debouncing, and digital logic applications.
