Nexperia USA Inc. 74LVC1G07GV,125

Overview

74LVC1G07GV,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 74LVC1G07GV,125 datasheet, 74LVC1G07GV,125 pinout, 74LVC1G07GV,125 application, or 74LVC1G07GV,125 equivalent, this device serves as a robust voltage-tolerant buffer for mixed-supply bus interfacing, requiring precise open-drain timing, low static current (<4 μA), and guaranteed operation from -40 °C to +125 °C.

Technical Context

This IC implements a single-channel CMOS buffer with true open-drain output architecture-no internal pull-up-enabling wired-AND configurations and bidirectional bus arbitration. Input tolerance up to 5.5 V allows safe connection to 5 V sources while powered from 1.65 V–3.3 V rails.

The IOFF circuit actively disables output leakage when VCC = 0 V, preventing backfeed current during hot-swap or partial power-down sequences. Schmitt-trigger input thresholds (e.g., 1.7 V typical VIH at 2.3–2.7 V VCC) ensure reliable switching with slow-rising signals common in sensor and mechanical switch interfaces.

FAQ

Can 74LVC1G07GV,125 drive an I²C bus directly?

Yes-it is explicitly designed for I²C and SMBus applications. Its open-drain output, 5.5 V input tolerance, and -24 mA sink capability at 3.0 V allow direct connection to standard I²C buses with appropriate external pull-up resistors. Propagation delay (≤5.5 ns at 3.3 V) ensures timing compliance up to 400 kHz Fast-mode operation without added latency.

What is the purpose of the n.c. pin on 74LVC1G07GV,125?

Pin 1 is a no-connect terminal with no internal bond wire or silicon connection. It must remain unconnected on the PCB-no trace, pad, or thermal relief should attach to it. This design choice accommodates package standardization across multiple variants (e.g., 74LVC1G07GW) while maintaining mechanical compatibility and mold integrity.

Does 74LVC1G07GV,125 require external pull-up resistors?

Yes-its open-drain output cannot source current. An external pull-up resistor to a defined voltage rail (e.g., 3.3 V or 5 V) is mandatory to establish the HIGH logic level. Typical values range from 1.8 kΩ (for 100 kHz) to 10 kΩ (for low-power standby), selected based on bus capacitance, rise time requirements, and power budget.

How does IOFF protect during partial power-down?

When VCC drops to 0 V, the IOFF circuit disables the output FET gate drive, forcing the Y pin into a high-impedance state with ±2 μA max leakage. This prevents current from flowing backward from a powered bus (e.g., 5 V I²C line) into the unpowered IC, avoiding latch-up, data corruption, or damage to upstream drivers during staged power cycling.
