Nexperia USA Inc. 74LVC1G07GW,125

Overview

74LVC1G07GW,125 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 partial power-down protection, and operates across 1.65 V to 5.5 V supply. Its -24 mA sink capability at 3.0 V enables direct interface with I²C, SMBus, and GPIO expansion in industrial control and sensor interface modules.

For engineers reviewing the 74LVC1G07GW,125 datasheet, 74LVC1G07GW,125 pinout, 74LVC1G07GW,125 application, or 74LVC1G07GW,125 equivalent, this device is selected for mixed-voltage signal buffering where rail-to-rail input tolerance, low quiescent current (0.1 μA typical), and guaranteed operation up to +125 °C are required - especially in battery-backed systems and automotive body electronics.

Technical Context

The 74LVC1G07GW,125 implements a single-stage CMOS buffer with open-drain output architecture, enabling wired-AND configurations and bidirectional bus driving when paired with external pull-ups. Its Schmitt-trigger input threshold (VIH = 0.7VCC, VIL = 0.3VCC) ensures robust timing margin against slow-rising signals from mechanical switches or long traces.

IOFF circuitry actively disables the output path when VCC = 0 V, blocking backflow current up to ±2 mA and meeting JEDEC JESD78 Class II latch-up immunity (>250 mA). The device complies with multiple JEDEC voltage standards (JESD8-7, JESD8-5, JESD8C, JESD36) and supports dynamic operation down to 1.65 V with propagation delay as low as 0.5 ns at 5.0 V.

FAQ

Can the 74LVC1G07GW,125 be used as a level shifter between 1.8 V and 5 V logic?

Yes - its overvoltage-tolerant inputs accept up to 5.5 V regardless of VCC, and its open-drain output can be pulled up to any voltage ≤5.5 V. When powered from 1.8 V, it safely translates 5 V inputs to 1.8 V-compatible output states, provided the external pull-up is connected to the target rail. No additional components are needed.

What is the maximum capacitive load the 74LVC1G07GW,125 can drive on its Y output?

The device is characterized for 30–50 pF loads per test conditions in Table 10, but real-world drive capability depends on required rise time and pull-up value. With a 2.2 kΩ pull-up to 3.3 V, it reliably drives up to 100 pF while maintaining <1 μs rise time. For heavier loads, reduce pull-up resistance or add a second stage.

Does the 74LVC1G07GW,125 require a pull-up resistor on the Y pin?

Yes - the open-drain output cannot source current; a pull-up resistor is mandatory to establish a valid HIGH logic level. Typical values range from 1 kΩ (for speed-critical 100 kHz I²C) to 10 kΩ (for low-power GPIO wake-up lines). No internal pull-up exists.

How does the IOFF feature behave during power sequencing?

When VCC drops below ~0.8 V, the IOFF circuit automatically disables the output FET, presenting a high-impedance state at Y and blocking reverse current flow from external pull-ups or driven buses. This occurs independently of input state and prevents backfeeding into a partially powered system - verified per JEDEC JESD78.
