Nexperia USA Inc. 74HC132D,652

Overview

74HC132D,652 from Nexperia is a quad 2-input NAND gate with Schmitt-trigger inputs in SO14 (SOT108-1) package, operating from 2.0 V to 6.0 V supply, delivering hysteresis of 0.6–1.6 V and propagation delay as low as 10 ns at 6.0 V, used for waveform shaping and relaxation oscillator circuits in industrial timing applications.

For engineers reviewing the 74HC132D,652 datasheet, 74HC132D,652 pinout, 74HC132D,652 application, or 74HC132D,652 equivalent, this device serves as a noise-immune digital logic element where input signal conditioning, jitter-free edge generation, and stable multivibrator operation are required under −40 °C to +125 °C conditions.

Technical Context

The 74HC132D,652 implements four independent NAND gates, each with asymmetric Schmitt-trigger input thresholds (VT+ = 1.7–5.9 V, VT− = 0.3–4.2 V depending on VCC), enabling robust noise rejection on slow-rising or noisy signals. Its CMOS architecture ensures low static current (≤40 μA at 6.0 V) and high noise immunity across temperature.

It supports unlimited input rise/fall times and includes clamp diodes allowing interface to voltages exceeding VCC via current-limiting resistors. Latch-up performance exceeds 100 mA per JESD78 Class II Level B, and ESD protection meets HBM >2000 V and CDM >1000 V.

FAQ

Can 74HC132D,652 operate reliably at 2.0 V supply?

Yes. The 74HC132D,652 is fully specified down to 2.0 V: VIH(min) = 1.9 V, VIL(max) = 0.1 V, and tpd ≤125 ns at 2.0 V with CL = 50 pF. It maintains functional Schmitt thresholds and latch-up immunity across the full −40 °C to +125 °C range at this voltage.

What is the maximum recommended capacitive load per output?

The datasheet specifies dynamic characterization at CL = 15 pF and 50 pF. While no absolute maximum is stated, sustained loading beyond 75 pF degrades tpd and increases transition time and power dissipation. For reliable 25 ns operation at 6.0 V, keep CL ≤50 pF and use series termination if routing to long traces.

Does the SO14 package include an exposed thermal pad?

No. The SOT108-1 (SO14) package used for 74HC132D,652 has no exposed thermal pad. Thermal dissipation relies on PCB copper area connected to pins 7 (GND) and 14 (VCC). For high-duty-cycle operation, use ≥2 cm² of 2-oz copper pour tied to both pins via multiple vias.

How does input clamping affect interfacing with 12 V signals?

Clamp diodes allow safe connection of inputs to voltages > VCC when used with a series current-limiting resistor. For 12 V input at VCC = 5 V, a 10 kΩ resistor limits IIK to <0.7 mA - well below the ±20 mA absolute maximum, preventing damage while preserving logic thresholds.
