Nexperia USA Inc. 74LVC2G32GN,115

Overview

74LVC2G32GN,115 from Nexperia is a dual 2-input OR gate logic IC in XSON8 package (SOT1116), operating from 1.65 V to 5.5 V supply, featuring 5 V-tolerant inputs, Schmitt-trigger inputs for noise immunity, and IOFF partial power-down protection. It enables level translation between 3.3 V and 5 V domains in compact space-constrained digital interfaces.

For engineers reviewing the 74LVC2G32GN,115 datasheet, 74LVC2G32GN,115 pinout, 74LVC2G32GN,115 application, or 74LVC2G32GN,115 equivalent, this device serves as a low-power, high-noise-immunity dual OR gate with verified 24 mA output drive at 3.0 V, -40 °C to +125 °C operation, and JEDEC-compliant ESD robustness (HBM >2000 V).

Technical Context

This device implements two independent OR logic functions with Schmitt-trigger inputs that accept slow-rising/falling signals without oscillation, enabling reliable interfacing with mechanical switches or noisy sensor outputs. Each gate supports rail-to-rail input voltage range up to 5.5 V regardless of VCC.

The IOFF circuit actively disables outputs when VCC = 0 V, blocking backflow current during hot-insertion or partial system power-down-critical for mixed-voltage board architectures. Propagation delay ranges from 0.7 ns (at 5 V) to 11 ns (at 1.65 V, -40 °C to +85 °C), with guaranteed timing across full temperature range.

FAQ

Can 74LVC2G32GN,115 operate with VCC = 1.65 V while accepting 5 V inputs?

Yes. The device is fully specified for 1.65 V to 5.5 V supply and features overvoltage-tolerant inputs rated to 5.5 V. This allows safe interfacing with 5 V signals even when powered from 1.65 V, enabling voltage translation without external components. Input thresholds scale with VCC, ensuring correct logic interpretation across the full supply range.

What is the purpose of the IOFF feature, and how does it behave during power-down?

The IOFF circuit disables both outputs when VCC = 0 V, limiting output leakage to ±2 μA maximum. This prevents damaging backflow current from powered downstream circuits into the unpowered IC-critical during hot-plug events or partial system shutdown. IOFF activates automatically; no external control signal is required.

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

Schmitt-trigger inputs provide hysteresis (~0.3 V typical), meaning the threshold for rising edges (VIH) is higher than for falling edges (VIL). This prevents multiple toggles when input signals cross the threshold slowly or contain noise, making the device immune to glitches under 10 ns and suitable for direct switch or sensor interfacing without external filtering.

Is the 74LVC2G32GN,115 pin-compatible with other packages in the 74LVC2G32 series?

No. While functionally identical, the GN variant uses SOT1116 (XSON8: 1.2 × 1.0 mm), whereas DP (TSSOP8), DC (VSSOP8), GT (XSON8: 1 × 1.95 mm), GS (XSON8: 1.35 × 1.0 mm), and GX (X2SON8: 1.35 × 0.8 mm) have distinct footprints and pinouts. Layout must be tailored to SOT1116 mechanical dimensions and terminal mapping.
