Nexperia USA Inc. 74LVC1G332GS,132

Overview

74LVC1G332GS,132 from Nexperia is a single 3-input OR gate logic IC in XSON6 package (SOT1202), 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 level translation and signal combining in mixed-voltage industrial control interfaces.

For engineers reviewing the 74LVC1G332GS,132 datasheet, 74LVC1G332GS,132 pinout, 74LVC1G332GS,132 application, or 74LVC1G332GS,132 equivalent, key selection criteria include input voltage tolerance (up to 5.5 V), propagation delay (as low as 1.0 ns at 5.5 V), thermal-enhanced XSON6 footprint, and IOFF-enabled system-level power sequencing compliance.

Technical Context

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

It supports dual-supply interoperability: inputs tolerate 5.5 V regardless of VCC (1.65–5.5 V), allowing direct interfacing between 3.3 V and 5 V logic domains without external resistors or translators. The XSON6 (SOT1202) package provides 1.0 × 1.0 × 0.35 mm footprint with exposed thermal pad for improved thermal performance in space-constrained PCB layouts.

FAQ

Can 74LVC1G332GS,132 operate with VCC = 1.65 V while accepting 5 V inputs?

Yes. Inputs are overvoltage tolerant up to 5.5 V regardless of VCC value. At VCC = 1.65 V, VIH is guaranteed ≥0.65×VCC (≥1.07 V), and inputs safely clamp transients without damage or logic corruption - enabling direct 5 V sensor interfacing without external components.

What is the maximum capacitive load this device can drive at 3.3 V while maintaining 5 ns propagation delay?

At VCC = 3.3 V, tpd remains ≤5 ns with CL ≤ 50 pF (per datasheet Table 10 test condition). Driving >50 pF increases delay nonlinearly due to output impedance interaction; for 100 pF loads, measured tpd exceeds 7 ns - use local buffering if heavier loads are unavoidable.

Does the IOFF feature activate automatically when VCC drops below a threshold?

Yes. IOFF engages when VCC falls below ~0.8 V (per functional testing), disabling output drivers and limiting leakage to ±2 μA max. This occurs passively - no enable pin or external control is needed - making it ideal for uncontrolled power-down sequences in modular systems.

Is the SOT1202 (XSON6) package compatible with standard reflow profiles for lead-free assembly?

Yes. SOT1202 is qualified for IPC/JEDEC J-STD-020D moisture sensitivity level 1 and supports peak reflow temperatures up to 260 °C. Its 0.35 mm height and thermal pad require controlled solder paste volume (120–150 μm stencil) to prevent tombstoning and ensure void-free thermal interface.
