NXP Semiconductors 74LVC1G332GXZ

Overview

74LVC1G332GXZ from Nexperia is a single 3-input OR gate logic IC with Schmitt-trigger inputs, IOFF partial power-down capability, and dual-voltage translation (1.65 V to 5.5 V supply), delivering ±24 mA output drive at 3.0 V and operating across –40 °C to +125 °C. It enables robust signal combining in mixed-voltage I/O interfaces such as industrial sensor hubs and low-power microcontroller peripheral expansion.

For engineers reviewing the 74LVC1G332GXZ datasheet, 74LVC1G332GXZ pinout, 74LVC1G332GXZ application, or 74LVC1G332GXZ equivalent, key selection criteria include input voltage tolerance (up to 5.5 V), propagation delay (as low as 1.0 ns at 4.5–5.5 V), IOFF-enabled backflow prevention during power sequencing, and X2SON6 package thermal performance for space-constrained PCB layouts.

Technical Context

This device implements standard positive-logic OR functionality (Y = A + B + C) with hysteresis on all inputs, enabling reliable operation with slow-rising or noisy signals. Its IOFF circuit actively disables outputs when VCC = 0 V, blocking reverse current flow between powered and unpowered domains.

It supports level translation across 1.65 V–5.5 V supply rails without external biasing, and meets JEDEC standards JESD8-7, JESD8-5, JESD8C, and JESD36 for interoperability with legacy TTL and modern low-voltage CMOS systems.

FAQ

Does 74LVC1G332GXZ support true 5 V TTL input compatibility?

Yes. Inputs tolerate up to 5.5 V regardless of VCC level, and VIH thresholds scale with supply voltage (e.g., 0.7 × VCC at 4.5–5.5 V), ensuring reliable recognition of 5 V TTL HIGH levels even when powered from 1.8 V or 3.3 V rails - no level-shifter required.

Can 74LVC1G332GXZ be used in hot-swap applications?

Yes. The IOFF circuit automatically places outputs in high-impedance state when VCC = 0 V, preventing damaging back-current flow from live backplane traces into the unpowered IC - a key requirement for PCIe add-in cards and modular industrial controllers.

What is the thermal performance advantage of the X2SON6 (SOT1255-2) package?

The X2SON6 package features a thermally enhanced die-pad structure and reduced body height (0.32 mm), achieving lower junction-to-board thermal resistance than standard XSON6 variants - critical for maintaining <125 °C junction temperature in dense, fanless enclosures with ambient up to 85 °C.

Is the 74LVC1G332GXZ pinout compatible with other 6-pin logic gates in X2SON6?

No. The pinout (A-GND-B-Y-VCC-C) is specific to this OR gate and differs from inverters, buffers, or NAND gates in the same package - e.g., 74LVC1G00 uses A-GND-B-Y-VCC-C but with inverted logic, while 74LVC1G14 (Schmitt inverter) maps input to Pin 1 and output to Pin 5. Layout reuse requires verification per datasheet.
