الوصف

نظرة عامة على المنتج

The 74HC132D from Nexperia is a quad 2-input NAND gate with Schmitt trigger inputs. Each of the four gates features hysteresis on its inputs, allowing slow-rising or noisy signals to be cleanly converted to sharp digital outputs. Operating from 2V to 6V supply, it is ideal for signal conditioning, debounce, oscillator, and waveform shaping circuits in digital and mixed-signal designs. Packaged in SOIC-14.

مقدمة المنتج:74HC132D مقدمة المنتج

The 74HC132D from Nexperia is a quad 2-input NAND gate with Schmitt trigger inputs providing ~0.6V hysteresis for clean switching on slow or noisy signals. Operating from 2V to 6V with 11 ns propagation delay, it is the standard solution for switch debounce, RC oscillators, waveform shaping, and signal conditioning in digital and mixed-signal designs. The SOIC-14 package uses the same pinout as 74HC00 for easy upgrade.

مبدأ العمل:74HC132D مبدأ العمل

The 74HC132D contains four independent 2-input NAND gates, each with Schmitt trigger input stages. A Schmitt trigger has two different threshold voltages: VT+ (positive-going) and VT- (negative-going). The difference between them is the hysteresis voltage (~0.6V at 4.5V supply). When the input rises above VT+, the output switches LOW (NAND function). When the input falls below VT-, the output switches HIGH. This hysteresis prevents output oscillation when the input signal is slow-moving or contains noise near the threshold. As a NAND gate, the output is LOW only when both inputs are above their positive thresholds, and HIGH otherwise. The Schmitt trigger inputs allow the device to accept slowly changing signals that would cause conventional gates to oscillate or draw excessive supply current.
