Nexperia USA Inc. 74LV32APWJ

Overview

74LV32APWJ from Nexperia is a quad 2-input OR gate logic IC with overvoltage-tolerant inputs, Schmitt-trigger input action, and IOFF partial power-down capability. It operates across 2.0 V to 5.5 V supply, delivers ≤9.5 ns propagation delay at 5 V, and supports mixed-voltage translation in level-shifting interfaces. It is used in industrial control I/O conditioning and low-power embedded system bus management.

For engineers reviewing the 74LV32APWJ datasheet, 74LV32APWJ pinout, 74LV32APWJ application, or 74LV32APWJ equivalent, key selection criteria include its 3.3 V output drive strength (VOH > 2.3 V / VOL < 0.44 V), -40 °C to +125 °C extended temperature rating, IOFF leakage < 0.5 μA during power-down, and TSSOP14 package compatibility with high-density PCB layouts.

Technical Context

The device implements four independent OR logic functions with Schmitt-trigger inputs that tolerate slow-rising signals and reject noise on digital control lines. Each gate features overvoltage-tolerant inputs rated up to 7.0 V, enabling safe interfacing between 3.3 V logic and 5 V or legacy systems without external clamping.

Its IOFF circuit actively disables outputs when VCC = 0 V, blocking backflow current and protecting downstream components during hot-swap or partial system power-down sequences. Static and dynamic characteristics are fully specified across -40 °C to +125 °C, with propagation delay tightly bounded (e.g., 4.2 ns typ / 9.5 ns max at 3.3 V, CL = 50 pF).

FAQ

Does the 74LV32APWJ support true bidirectional level translation?

No - it is a unidirectional OR gate with overvoltage-tolerant inputs, not a bidirectional translator. Inputs accept up to 7.0 V regardless of VCC, but outputs swing only between GND and VCC. For true bidirectional translation, a dedicated bus switch or dual-supply level shifter is required.

Can the IOFF feature be used with VCC = 3.3 V while inputs are held at 5 V?

Yes - IOFF activates only when VCC = 0 V; it does not depend on input voltage. With VCC = 3.3 V and inputs at 5 V, the device operates normally (inputs are overvoltage-tolerant), and outputs drive within 3.3 V logic levels. IOFF is irrelevant unless VCC is fully removed.

What is the maximum capacitive load the 74LV32APWJ can drive while maintaining 9.5 ns tpd?

The 9.5 ns maximum propagation delay is specified at CL = 50 pF and VCC = 4.5–5.5 V. Driving loads >50 pF increases tpd nonlinearly; for example, at CL = 75 pF, tpd exceeds 11 ns. Keep total load (including trace and input capacitance) ≤50 pF for guaranteed timing compliance.

Is the 74LV32APWJ pin-compatible with older 74LV32 variants like the 74LV32D?

Yes - both use the same TSSOP14 (SOT402-1) package and identical pinout per JEDEC MO-153. The 'PWJ' suffix denotes tape-and-reel packaging with moisture sensitivity level 1 (MSL-1), but electrical and mechanical compatibility is maintained with legacy 'D' and 'PW' variants.
