Nexperia USA Inc. 74LVC1G07GX4Z

Overview

74LVC1G07GX4Z from Nexperia is a single non-inverting buffer with open-drain output, designed for level translation between 3.3 V and 5 V logic domains. It features Schmitt-trigger inputs for noise immunity, IOFF circuitry for partial power-down protection, and operates across 1.65 V to 5.5 V supply. Its X2SON4 package (SOT1269-2) supports high-density PCB layouts in I²C bus pull-up, LED driving, and wired-OR logic applications.

For engineers reviewing the 74LVC1G07GX4Z datasheet, 74LVC1G07GX4Z pinout, 74LVC1G07GX4Z application, or 74LVC1G07GX4Z equivalent, key selection criteria include open-drain drive capability (-24 mA at VCC = 3.0 V), input overvoltage tolerance to 5.5 V, -40 °C to +125 °C operating range, and thermal-enhanced X2SON4 footprint compatibility with automated optical inspection (AOI) and reflow processes.

Technical Context

This device implements a single-channel CMOS buffer with true open-drain output architecture, enabling bidirectional signal translation without internal pull-ups. The Schmitt-trigger input threshold (VIH = 0.7VCC, VIL = 0.3VCC at VCC ≥ 4.5 V) ensures robust operation with slow-rising signals, while IOFF functionality disables output leakage when VCC = 0 V.

It complies with JEDEC standards JESD8-7, JESD8-5, JESD8C, and JESD36 across its full 1.65–5.5 V supply range and meets HBM ESD >2000 V and CDM >1000 V per JS-001/JS-002. Propagation delay is 0.5–4.5 ns depending on VCC, with typical tpd = 1.6 ns at 5.0 V.

FAQ

What is the maximum sink current capability of the 74LVC1G07GX4Z output?

The 74LVC1G07GX4Z output can sink up to -24 mA when VCC = 3.0 V and VO ≤ 0.55 V, as specified in Table 7 of the datasheet. At VCC = 5.0 V, it sustains -32 mA with VO ≤ 0.55 V. This rating applies under steady-state DC conditions with proper PCB copper pour for thermal dissipation.

Can the 74LVC1G07GX4Z be used with a 1.8 V supply?

Yes - the device is fully specified from 1.65 V to 5.5 V. At VCC = 1.8 V, VIH = 1.17 V min and VIL = 0.54 V max per Table 7, and propagation delay is 2.6 ns typical. Input overvoltage tolerance remains active, allowing 3.3 V or 5 V signals to be safely applied.

Does the 74LVC1G07GX4Z require external pull-up resistors?

Yes - the open-drain output requires an external pull-up resistor to define the HIGH logic state. Typical values range from 1 kΩ (for 1 MHz I²C) to 10 kΩ (for low-power GPIO wake-up). No internal pull-up is present; leaving Y unconnected results in floating HIGH-impedance state.

How does the IOFF feature protect the device during power sequencing?

When VCC = 0 V, the IOFF circuitry disables the output FET, limiting OFF-state leakage to ±2 μA maximum (Table 7). This prevents damaging backflow current from powered downstream circuits into the unpowered buffer, ensuring safe hot-insertion in modular systems with staggered power rails.
