Nexperia USA Inc. 74LVC1G332GN,132

Overview

74LVC1G332GN,132 from Nexperia is a single 3-input OR gate logic IC in XSON6 package (SOT1115), operating from 1.65 V to 5.5 V supply, featuring Schmitt-trigger inputs for noise immunity, IOFF partial power-down protection, and ±24 mA output drive at 3.0 V - used in voltage-level translation between 3.3 V and 5 V subsystems in industrial control I/O conditioning.

For engineers reviewing the 74LVC1G332GN,132 datasheet, 74LVC1G332GN,132 pinout, 74LVC1G332GN,132 application, or 74LVC1G332GN,132 equivalent, key selection criteria include input overvoltage tolerance to 5.5 V, guaranteed operation from –40 °C to +125 °C, propagation delay as low as 1.0 ns at 5.0 V, IOFF leakage < ±2 μA during power-down, and compatibility with TTL input levels.

Technical Context

This device implements a single 3-input positive-logic OR function (Y = A + B + C) with Schmitt-trigger inputs enabling robust operation with slow-rising or noisy signals. Its IOFF circuit actively disables outputs when VCC = 0 V, preventing backflow current in mixed-voltage hot-swap or partial-power-down systems.

The logic core uses CMOS technology with rail-to-rail output swing, specified across 1.65–5.5 V supply range and qualified per JEDEC standards JESD8-7, JESD8-5, JESD8C, and JESD36. Input thresholds scale with VCC (e.g., VIH = 0.7×VCC at 4.5–5.5 V), ensuring reliable interfacing with both LVTTL and LVCMOS sources.

FAQ

Can 74LVC1G332GN,132 operate with 1.8 V supply and interface to 5 V inputs?

Yes. The device is fully specified from 1.65 V to 5.5 V supply and accepts input voltages up to 5.5 V regardless of VCC level. At VCC = 1.8 V, VIH is 0.65×VCC ≈ 1.17 V and VIL is 0.35×VCC ≈ 0.63 V, enabling reliable detection of 5 V TTL logic highs while powered from 1.8 V rails - no external level shifters required.

What is the significance of the IOFF feature in practical system design?

IOFF disables the output buffer and blocks current flow through the device when VCC = 0 V. This prevents back-current from externally biased inputs (e.g., 5 V signals) into a powered-down section of the system - essential for hot-swap connectors, modular backplanes, and multi-rail power sequencing where subsystems power up/down independently.

How does the Schmitt-trigger input improve noise immunity compared to standard CMOS inputs?

Schmitt-trigger inputs have hysteresis: VIH is ~1.7 V and VIL is ~0.7 V at VCC = 2.7 V, creating a 1.0 V noise margin. This rejects short-duration noise spikes and accommodates slow input edges (e.g., from RC-filtered sensors or mechanical switches) without oscillation - unlike standard CMOS inputs which switch near VCC/2 and are prone to metastability on noisy or slow transitions.

Is the 74LVC1G332GN,132 suitable for automotive applications?

No. Although rated for –40 °C to +125 °C, this part is not AEC-Q200 qualified and lacks automotive-specific validation (e.g., HTOL, EFT, ISO 10605). Nexperia explicitly states non-automotive qualification in its legal disclaimers. For automotive use, select the AEC-Q200 qualified 74LVC1G332GW-Q100 variant instead.
