Nexperia USA Inc. 74LVC3G07GD,125

Overview

74LVC3G07GD,125 from Nexperia is a triple non-inverting buffer IC with open-drain outputs, designed for level translation and wired-OR logic implementation in mixed-voltage systems. It operates from 1.65 V to 5.5 V, accepts 5 V-tolerant inputs, features Schmitt-trigger inputs for noise immunity, and supports IOFF partial power-down protection. It is used in I²C bus buffering, LED driver interface, and voltage-level shifting between 3.3 V and 5 V domains.

For engineers reviewing the 74LVC3G07GD,125 datasheet, 74LVC3G07GD,125 pinout, 74LVC3G07GD,125 application, or 74LVC3G07GD,125 equivalent, key selection criteria include open-drain drive capability (–24 mA at VCC = 3.0 V), wide supply range (1.65–5.5 V), –40 °C to +125 °C operation, IOFF-enabled power-down isolation, and XSON8 package compatibility with high-density PCB layouts.

Technical Context

This device implements three independent non-inverting buffers, each with an open-drain output stage enabling wired-AND/wired-OR logic when multiple outputs share a common pull-up. Its Schmitt-trigger inputs accept slow-rising signals and reject noise, while the IOFF circuit disables all outputs when VCC = 0 V, preventing backflow current during hot-swap or partial power-down.

The logic function is strictly buffer-only: input HIGH yields high-impedance output (unless pulled low externally); input LOW pulls output to GND. Propagation delay ranges from 0.5 ns (VCC = 5.5 V) to 8.4 ns (VCC = 1.65 V, Tamb = –40 °C to +125 °C), with dynamic power dissipation governed by CPD = 6.5 pF at VCC = 3.3 V.

FAQ

Can 74LVC3G07GD,125 drive a 5 V pull-up resistor while powered at 3.3 V?

Yes. Its inputs and outputs are 5 V tolerant, meaning it can safely interface with 5 V pull-ups while operating at VCC = 3.3 V. The open-drain output will sink current to GND when active, and present high impedance when inactive - allowing the 5 V pull-up to establish the HIGH state without damaging the IC.

Does this device support true bidirectional I²C buffering?

No. The 74LVC3G07GD,125 provides unidirectional buffering only. It lacks internal direction control or bus-hold circuitry required for true bidirectional I²C repeaters. It can buffer SDA or SCL in one direction (e.g., master-to-slave), but cannot handle arbitration or clock stretching without external logic.

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

Per datasheet test conditions, it drives up to 50 pF with guaranteed timing (tpd ≤ 4.7 ns at VCC = 3.3 V). For loads exceeding 50 pF, propagation delay increases and rise/fall times degrade - use series termination or reduce trace length to maintain signal integrity in high-capacitance bus applications.

How does IOFF protect the device during power sequencing?

When VCC = 0 V, the IOFF circuit disables all outputs, limiting OFF-state leakage to ±2 μA. This prevents current from flowing backward through the output FETs from a live bus (e.g., 5 V I²C line) into the unpowered IC, avoiding latch-up or damage during hot-plug or staggered power-up sequences.
