Nexperia USA Inc. 74LVC1G02GV,125

Overview

74LVC1G02GV,125 from Nexperia is a single 2-input NOR gate logic IC in SC-74A (SOT753) package, 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 for level translation and signal conditioning in mixed-voltage digital interfaces.

For engineers reviewing the 74LVC1G02GV,125 datasheet, 74LVC1G02GV,125 pinout, 74LVC1G02GV,125 application, or 74LVC1G02GV,125 equivalent, key selection criteria include input overvoltage tolerance to 5.5 V, propagation delay down to 0.5 ns at 5 V, -40 °C to +125 °C operation, and compatibility with TTL-level drivers in space-constrained industrial control and portable electronics.

Technical Context

This device implements a single 2-input NOR function with true CMOS architecture, enabling rail-to-rail output swing and low static current (≤4 μA). Its Schmitt-trigger inputs provide hysteresis (typically 0.3 V at 3.3 V), allowing 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 ±2 mA - critical for hot-swap and multi-rail power sequencing. Input voltage tolerance to 5.5 V permits direct interfacing with 5 V legacy logic while powered from 1.8 V or 3.3 V rails.

FAQ

Does 74LVC1G02GV,125 support 5 V input signals while powered from 1.8 V?

Yes. Its inputs are overvoltage tolerant up to 5.5 V independent of VCC, enabling direct connection to 5 V microcontroller outputs even when VCC = 1.65 V–1.95 V. This eliminates external level-shifting components in mixed-voltage designs.

What is the maximum capacitive load this device can drive reliably?

At VCC = 3.3 V and Tamb = 25 °C, the device drives up to 50 pF with tpd ≤ 4.5 ns (typical). For heavier loads (>75 pF), propagation delay increases linearly; design margin requires verifying setup/hold timing against downstream receivers.

How does the IOFF feature behave during power-down sequences?

When VCC drops below ~0.2 V, the IOFF circuit forces the Y output into high-impedance state within 100 ns, limiting backflow current to ≤±2 μA. This prevents unintended powering of upstream circuits via the output pin during brown-out or controlled shutdown.

Is the SC-74A (SOT753) package compatible with standard reflow profiles?

Yes. The SOT753 package is qualified for IPC/JEDEC J-STD-020D reflow profiles, including peak temperatures up to 260 °C for ≤30 seconds. Its 0.95 mm pitch and gull-wing leads support automated optical inspection and standard solder paste stencil designs.
