الوصف

نظرة عامة على المنتج

The 74HC132D from Nexperia is a quad 2-input NAND gate with Schmitt-trigger inputs. The Schmitt-trigger action transforms slowly changing or noisy input signals into sharply defined, jitter-free output signals, making it ideal for wave shaping, oscillator, and debouncing circuits. With wide 2.0V to 6.0V supply, CMOS low power, and high noise immunity, it is available in an SOIC-14 package specified from -40°C to +125°C.

مقدمة المنتج:74HC132D مقدمة المنتج

The 74HC132D from Nexperia is a quad 2-input NAND gate with Schmitt-trigger inputs that transform slowly changing or noisy signals into clean, jitter-free outputs. With 2.0V to 6.0V supply, 11 ns propagation delay, high noise immunity, and CMOS low power in an SOIC-14 package rated to 125°C, it is ideal for wave shaping, RC oscillators, debounce circuits, and signal conditioning.

مبدأ العمل:74HC132D مبدأ العمل

The 74HC132D implements four independent 2-input NAND gates, each with Schmitt-trigger input stages. The Schmitt trigger introduces hysteresis into the input threshold: the positive-going threshold (VT+) is higher than the negative-going threshold (VT-). This hysteresis eliminates output oscillation when the input signal passes slowly through the switching region, as the output only transitions once the input crosses the appropriate threshold. This makes the device ideal for debouncing mechanical switches, conditioning slow or noisy signals, and building RC oscillators where the hysteresis defines the oscillation amplitude. The NAND function outputs LOW only when both inputs are HIGH, implementing Y = NOT(A AND B). Input clamp diodes protect against voltages exceeding VCC, allowing current-limiting resistor interface to higher voltage signals.
