Nexperia USA Inc. 74LVC1G02GS,132

Overview

74LVC1G02GS,132 from Nexperia is a single 2-input NOR gate logic IC in XSON6 (SOT1202) package, operating from 1.65 V to 5.5 V supply, featuring IOFF partial power-down protection, Schmitt-trigger inputs for noise immunity, and ±24 mA output drive at 3.0 V - used in level translation between 3.3 V and 5 V domains in industrial control I/O interfaces.

For engineers reviewing the 74LVC1G02GS,132 datasheet, 74LVC1G02GS,132 pinout, 74LVC1G02GS,132 application, or 74LVC1G02GS,132 equivalent, key selection criteria include its 1.65–5.5 V wide VCC range, IOFF-enabled hot-swap capability, Schmitt-trigger input tolerance to slow edges, -40 °C to +125 °C temperature rating, and XSON6 footprint compatibility with high-density PCB layouts.

Technical Context

This device implements standard positive-logic NOR functionality (Y = NOT(A OR B)) with rail-to-rail CMOS output swing and input thresholds scaled to VCC (e.g., VIH = 0.7VCC at 4.5–5.5 V). Its Schmitt-trigger inputs provide hysteresis (typically 0.3 V at 3.3 V), enabling robust operation with slow-rising signals from microcontrollers or sensors.

The IOFF circuit actively disables outputs when VCC = 0 V, blocking backflow current up to ±50 mA - critical for live insertion in multi-rail systems. Propagation delay ranges from 0.5 ns (min) to 6.0 ns (max) at VCC = 3.0–3.6 V, with dynamic power dissipation governed by CPD = 14 pF.

FAQ

Can 74LVC1G02GS,132 safely interface a 5 V sensor output to a 3.3 V microcontroller?

Yes. Its inputs tolerate up to 5.5 V regardless of VCC voltage, and VIH/VIL thresholds scale with VCC - at 3.3 V supply, VIH = 2.0 V min and VIL = 0.8 V max, providing 1.2 V noise margin against 5 V logic levels. No external resistors or clamps are needed.

What happens to the output when VCC is disconnected during system operation?

The IOFF circuit detects VCC = 0 V and forces the Y output into high-impedance state, blocking back-current flow from other powered rails. Measured IOFF leakage is ≤±2 μA at 5.5 V applied to Y or A/B pins - preventing bus contention or latch-up in live-insertion scenarios.

Is the n.c. pin (Pin 5) required to be left floating, or can it be grounded?

Pin 5 is internally unconnected and must remain floating. Grounding it may cause unintended current paths or violate package thermal performance assumptions. The datasheet explicitly defines it as "not connected" - no bonding wire or internal connection exists.

How does Schmitt-trigger input behavior affect timing in slow-edge applications?

Schmitt-trigger inputs provide ~0.3 V hysteresis at 3.3 V, meaning the rising threshold is ~0.15 V higher than the falling threshold. This eliminates multiple toggling on noisy or slowly rising signals - e.g., a 100 µs rise-time switch input triggers only once, with propagation delay referenced to the defined switching point (VM = 0.5VCC).
