The SN74LVC14ADR from TI is a hex inverter with Schmitt-trigger inputs, operating at 3.3V with 5V-tolerant inputs. Schmitt hysteresis provides noise immunity and clean squaring of slowly-rising signals, making it essential for debouncing and clock conditioning.

Principio de funcionamiento
Each of the six channels inverts the input with hysteresis: the positive-going threshold (VT+) is higher than the negative-going threshold (VT-), providing ~300 mV hysteresis. This prevents multiple output transitions on noisy or slowly-changing inputs. 5V-tolerant inputs allow interfacing with 5V logic while powered from 3.3V.
Aplicaciones
- Switch debounce
- Clock squaring
- Noise filtering on digital inputs
- Sine-to-square conversion
