Nexperia USA Inc. 74LV7032APWJ

Overview

74LV7032APWJ from Nexperia is a quad 2-input OR gate IC with Schmitt-trigger inputs, designed for noise-immune signal conditioning in mixed-voltage digital systems. It operates from 2.0 V to 5.5 V, delivers ≤9.5 ns propagation delay at 5 V, supports IOFF partial power-down, and features overvoltage-tolerant inputs enabling level translation between 3.3 V and 5 V domains - used in industrial control I/O buffering and sensor interface signal cleanup.

For engineers reviewing the 74LV7032APWJ datasheet, 74LV7032APWJ pinout, 74LV7032APWJ application, or 74LV7032APWJ equivalent, key selection criteria include Schmitt-trigger hysteresis (0.5 V at 5 V), IOFF leakage <0.5 μA at VCC = 0 V, guaranteed operation from –40 °C to +125 °C, and TSSOP14 package compatibility with high-density PCB layouts.

Technical Context

This device implements four independent 2-input OR logic functions, each with integrated Schmitt-trigger input thresholds (VT+ = 3.5 V, VT– = 1.5 V at VCC = 5 V) to reject analog noise on slow-rising signals. The IOFF circuit actively disables outputs during power-down, blocking backflow current when VCC = 0 V while inputs remain biased at up to 7 V.

It complies with JEDEC JESD78 Class II latch-up immunity (>250 mA), supports mixed-mode voltage operation across all ports, and maintains defined logic states under transient supply collapse - making it suitable for hot-swap-capable subsystems and battery-backed peripheral interfaces.

FAQ

Does the 74LV7032APWJ support true bidirectional I/O?

No. It is a unidirectional quad OR gate with dedicated inputs (1A–4B) and outputs (1Y–4Y). While inputs tolerate overvoltage and outputs disable cleanly via IOFF, no pin functions as both input and output. Bidirectional operation requires external circuitry or a different device type such as a bus transceiver.

Can the 74LV7032APWJ be used with a 1.8 V supply?

No. The absolute minimum recommended supply voltage is 2.0 V per Table 5. At 1.8 V, static parameters like VOH and VOL fall outside specification, and Schmitt thresholds become undefined. For 1.8 V systems, consider the 74LVC1G32 or 74AUP1G32 families instead.

What is the maximum capacitive load the outputs can drive reliably?

The device is characterized up to 50 pF (Table 7), with tpd specified at CL = 15 pF and 50 pF. Driving >50 pF may increase propagation delay nonlinearly and risk output rise/fall time violations. For heavier loads, add a buffer stage or reduce trace capacitance via layout optimization.

Is the 74LV7032APWJ pin-compatible with older 74LV7032 variants?

Yes. The 74LV7032APWJ uses the same TSSOP14 (SOT402-1) pinout as legacy 74LV7032 and 74LV7032A versions. Pin assignments for inputs, outputs, GND, and VCC match exactly - enabling direct replacement without PCB modification.
