概述

Description

SN74HC14ANSR is TI’s hex Schmitt-trigger inverter from the 74HC family. It contains six independent Schmitt-trigger inverters (inverting buffers) with hysteresis, which cleanly convert slow or noisy input signals into sharp digital transitions.
Key points:
- Supply voltage: typically 2 to 6 V
- Six Schmitt-trigger gates in one 14‑pin package
- High noise immunity due to input hysteresis; low static power
- Fast CMOS switching (propagation delays on the order of a few to a few dozen nanoseconds, depending on Vcc and load)
- Suitable for debouncing, RC oscillator circuits, waveform shaping, and level restoration
Packaging note: SN74HC14ANSR denotes a specific 14‑pin package (often surface‑mount/tape‑and‑reel). Check the datasheet for exact electrical characteristics, pinout, and packaging details.

Features

SN74HC14ANSR is a Hex Schmitt-trigger inverter from the 74HC family. Key features:
