Nexperia USA Inc. 74HC132BQX

Overview

74HC132BQX from Nexperia is a quad 2-input NAND gate with Schmitt-trigger inputs, designed for noise-immune signal conditioning in digital logic interfaces. It operates from 2.0 V to 6.0 V, delivers hysteresis of 0.6–1.6 V (VCC = 2.0–6.0 V), supports −40 °C to +125 °C ambient range, and features 14-terminal DHVQFN package with thermal enhancement. It is used in wave shaping and relaxation oscillator circuits where slow or noisy input edges must be converted into clean TTL/CMOS-compatible outputs.

For engineers reviewing the 74HC132BQX datasheet, 74HC132BQX pinout, 74HC132BQX application, or 74HC132BQX equivalent, key selection criteria include Schmitt-trigger hysteresis voltage (VT+ / VT−), propagation delay (10–38 ns depending on VCC and load), supply current (≤40 μA at VCC = 6.0 V), input clamping diode support for overvoltage-tolerant interfacing, and DHVQFN14 thermal performance in space-constrained PCB layouts.

Technical Context

The 74HC132BQX implements four independent NAND gates, each with asymmetric Schmitt-trigger input thresholds-VT+ ranges from 0.7 V (VCC = 2.0 V) to 4.2 V (VCC = 6.0 V), and VT− from 0.3 V to 3.0 V-enabling robust noise rejection on slow-rising signals. Its CMOS architecture ensures low static power (ICC ≤ 40 μA) and high noise immunity (>50% of VCC).

Each gate's output drives up to ±25 mA, with VOL ≤ 0.4 V at IO = 5.2 mA and VOH ≥ 5.2 V at IO = −5.2 mA (VCC = 6.0 V). Input clamp diodes allow external current-limiting resistors for interfacing to voltages exceeding VCC, supporting mixed-voltage system integration without level shifters.

FAQ

What is the maximum allowable input voltage when VCC = 3.3 V?

The 74HC132BQX includes integrated input clamp diodes that permit input voltages up to VCC + 0.5 V (i.e., 3.8 V) when current is limited externally. Exceeding this requires series resistors sized to keep IIK ≤ ±20 mA, as specified in the Absolute Maximum Ratings table. Operation above VCC + 0.5 V without current limiting risks permanent damage.

Can the 74HC132BQX drive a 50 pF load at 10 MHz without signal degradation?

Yes-the 74HC132BQX exhibits tpd = 13 ns and tt = 7 ns (VCC = 4.5 V, CL = 50 pF), enabling clean 10 MHz square-wave output with <10% duty-cycle distortion. Its CPD = 24 pF ensures dynamic power remains low (<1.5 mW at 10 MHz), and its ±25 mA drive strength easily handles 50 pF with rise/fall times under 10 ns.

Is the exposed thermal pad on the DHVQFN14 package required to be soldered to ground?

No-the exposed pad (Pin 1 index area) has no electrical or mechanical requirement to be soldered. If soldered, it must remain electrically floating or be connected to GND; floating connection is acceptable and commonly used to simplify assembly. Thermal performance improvement is marginal unless thermally coupled to a large copper pour.

How does the hysteresis voltage change across temperature and supply voltage?

At VCC = 6.0 V, VH ranges from 0.6 V (min) to 1.6 V (max) across −40 °C to +125 °C. At VCC = 2.0 V, VH is 0.2–1.0 V. The hysteresis scales approximately linearly with VCC, and variation over temperature is bounded within datasheet min/max limits-ensuring consistent noise margin across full operating range without calibration.
