Nexperia USA Inc. 74LVC2G06GW,125

Overview

74LVC2G06GW,125 from Nexperia is a dual CMOS inverter with open-drain outputs, 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. Used in I²C bus pull-up interfaces, GPIO signal conditioning, and mixed-voltage microcontroller peripheral interfacing.

For engineers reviewing the 74LVC2G06GW,125 datasheet, 74LVC2G06GW,125 pinout, 74LVC2G06GW,125 application, or 74LVC2G06GW,125 equivalent, key selection criteria include open-drain drive capability (–24 mA at 3.0 V), input overvoltage tolerance (5.5 V), IOFF-enabled backflow prevention, and –40 °C to +125 °C industrial temperature rating.

Technical Context

This device implements two independent inverting buffers, each with an open-drain output requiring external pull-up. Inputs accept 3.3 V or 5 V signals regardless of VCC, enabling bidirectional voltage translation without direction control logic. Schmitt-trigger thresholds provide hysteresis (typically 0.3–0.5 V) to suppress noise on slow-rising signals.

The IOFF circuit actively disables both outputs when VCC = 0 V, blocking current flow from powered I/O lines into the unpowered device. Static and dynamic characteristics are fully specified across 1.65–5.5 V and –40 °C to +125 °C, with propagation delay as low as 0.5 ns at 5 V and 2.5 ns at 1.8 V.

FAQ

Can 74LVC2G06GW,125 drive an I²C bus directly?

Yes - its open-drain outputs meet I²C specification requirements when paired with appropriate pull-up resistors. At VCC = 3.3 V, it sinks up to 24 mA with VOL ≤ 0.55 V, supporting standard (100 kHz) and fast-mode (400 kHz) buses with typical 400 pF load. No additional buffering or level-shifting circuitry is needed for 3.3 V/5 V mixed-bus operation.

What happens to the outputs when VCC is disconnected?

When VCC = 0 V, the IOFF circuit activates and places both 1Y and 2Y outputs in high-impedance state, limiting leakage current to ±2 μA. This prevents back-current from externally pulled-up lines (e.g., 5 V I²C bus) into the unpowered device, protecting downstream circuitry during hot-swap or power sequencing events.

Is the Schmitt-trigger input threshold fixed or supply-dependent?

Schmitt-trigger thresholds are supply-dependent: typical hysteresis is 0.35 V at VCC = 1.8 V and increases to ~0.7 V at VCC = 5.0 V. VIH min is 0.65 × VCC and VIL max is 0.35 × VCC (at low VCC) or 0.3 × VCC (at 5 V), ensuring consistent noise margin across the full 1.65–5.5 V operating range.

Does 74LVC2G06GW,125 require external pull-up resistors on both outputs?

Yes - both 1Y and 2Y are true open-drain terminals with no internal pull-up. External resistors must be connected between each output and its respective pull-up voltage rail (e.g., 3.3 V or 5 V). Resistor value depends on bus capacitance and speed: 1 kΩ–10 kΩ is typical for I²C; lower values improve rise time but increase power consumption during LOW states.
