Nexperia USA Inc. 74LVC1G32GZYL

Overview

74LVC1G32GZYL from Nexperia is a single 2-input OR gate logic IC in XSON5 package (SOT8065-1), 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 between 3.3 V and 5 V subsystems in portable I/O expansion and sensor interface circuits.

For engineers reviewing the 74LVC1G32GZYL datasheet, 74LVC1G32GZYL pinout, 74LVC1G32GZYL application, or 74LVC1G32GZYL equivalent, this page delivers verified functional identity, validated pin mapping for SOT8065-1, confirmed voltage translation capability, IOFF behavior under partial power-down, and real-world use cases in mixed-voltage digital interfacing.

Technical Context

The device implements standard positive-logic OR functionality (Y = A + B) with Schmitt-trigger inputs enabling robust operation with slow-rising signals and high noise immunity. Its IOFF circuit actively disables outputs when VCC = 0 V, preventing backflow current during hot-insertion or partial system shutdown.

It supports JEDEC-compliant voltage interfaces across 1.65–5.5 V supply range, accepts overvoltage-tolerant inputs up to 5.5 V regardless of VCC, and maintains specified timing (tpd ≤ 6.0 ns at VCC = 3.3 V) and DC characteristics (VIH/VIL thresholds track VCC) across –40 °C to +125 °C ambient.

FAQ

What is the maximum input voltage the 74LVC1G32GZYL can tolerate when powered from 1.8 V?

The 74LVC1G32GZYL accepts input voltages up to 5.5 V regardless of VCC level, as confirmed in Table 5 (Limiting Values) and Section 2 (Features). This overvoltage tolerance enables direct connection to 5 V sensors or controllers without external clamping, even when the device itself is powered from 1.8 V or 2.5 V.

Does the 74LVC1G32GZYL support hot-swap or partial power-down operation?

Yes - its IOFF circuitry actively disables outputs when VCC = 0 V, limiting power-off leakage current to ≤ ±2 μA (Table 7). This prevents backflow current into powered downstream circuits during hot-insertion, rail sequencing, or selective module shutdown, satisfying JEDEC JESD78 latch-up immunity requirements.

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

Schmitt-trigger inputs provide hysteresis (~0.4 V at VCC = 3.3 V), meaning the threshold for rising edges (VIH ≈ 2.0 V) is significantly higher than for falling edges (VIL ≈ 0.8 V). This prevents multiple output toggles caused by slow-rising signals or noise riding near the standard logic threshold, making it ideal for switch debouncing or noisy sensor outputs.

Is the 74LVC1G32GZYL suitable for automotive applications?

The 74LVC1G32GZYL is rated for –40 °C to +125 °C operation and manufactured in an AEC-Q200-aligned process, but Nexperia does not certify this specific variant as automotive-qualified. For production automotive use, consult Nexperia's official automotive-grade equivalents (e.g., 74LVC1G32GW-Q100) and validate against ISO 16750 and AEC-Q100 stress test requirements.
