Nexperia USA Inc. 74HCT132PW,118

Overview

74HCT132PW,118 from Nexperia is a quad 2-input NAND gate with Schmitt-trigger inputs in a TSSOP14 package, operating from 4.5 V to 5.5 V, delivering hysteresis of 0.4–0.6 V (VCC = 4.5–5.5 V), propagation delay as low as 17 ns at 5 V, and rated for −40 °C to +125 °C ambient. It transforms slow-rising input signals into clean digital outputs in waveform shaping and relaxation oscillator circuits.

For engineers reviewing the 74HCT132PW,118 datasheet, 74HCT132PW,118 pinout, 74HCT132PW,118 application, or 74HCT132PW,118 equivalent, key selection criteria include Schmitt-trigger hysteresis voltage, TTL-compatible input thresholds (VT+ = 1.2–2.1 V, VT− = 0.5–1.4 V), output drive strength (±4 mA), thermal performance in TSSOP14 (7.3 mW/K derating above 81 °C), and compatibility with 5 V logic systems requiring noise-immune signal conditioning.

Technical Context

The 74HCT132PW,118 implements four independent NAND gates, each with dual Schmitt-trigger inputs that provide distinct positive- and negative-going threshold voltages (e.g., VT+ = 1.41 V, VT− = 0.85 V at VCC = 4.5 V), enabling robust noise rejection on slow analog-like inputs. Its TTL-compatible input levels allow direct interfacing with legacy 5 V logic families without level shifting.

Each gate's output drives ±4.0 mA at VOH ≥ 3.98 V and VOL ≤ 0.26 V under recommended conditions, supporting fan-out to standard CMOS/TTL loads. The device uses silicon-gate CMOS technology, ensuring static power dissipation below 2 μA at 25 °C and total power dissipation up to 500 mW (derated linearly above 81 °C in TSSOP14).

FAQ

What is the maximum allowable supply voltage for 74HCT132PW,118?

The absolute maximum supply voltage is +7 V, but the recommended operating range is strictly 4.5 V to 5.5 V. Exceeding 5.5 V risks violating input/output voltage limits and may cause accelerated parametric drift or latch-up. Operation at 7 V is only permitted transiently (≤200 ns) per IEC 60134 limiting values.

Can 74HCT132PW,118 drive an LED directly?

No - its output current rating is ±4.0 mA, insufficient to visibly illuminate most indicator LEDs (typically requiring 5–20 mA). Driving an LED directly risks exceeding VOL/VOH specifications and degrading noise margins. Use an external transistor or buffer stage for LED loads.

Is the exposed pad on the TSSOP14 package electrically connected?

No - the thermal pad in SOT402-1 (TSSOP14) is not electrically connected to any internal node. Nexperia documentation states it has no electrical or mechanical requirement to be soldered; if soldered, it must remain floating or tied to GND to avoid unintended coupling paths.

How does hysteresis improve performance in oscillator circuits?

Hysteresis creates distinct turn-on and turn-off thresholds, preventing output oscillation during slow input transitions. In relaxation oscillators built with 74HCT132PW,118, this ensures stable, jitter-free frequency generation determined solely by RC time constants-not input noise or propagation delay variations.
