NXP Semiconductors 74LVC3G06GD,125

Overview

74LVC3G06GD,125 from Nexperia is a triple inverter IC 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 buffering, LED sink drivers, and mixed-voltage GPIO interfacing.

For engineers reviewing the 74LVC3G06GD,125 datasheet, 74LVC3G06GD,125 pinout, 74LVC3G06GD,125 application, or 74LVC3G06GD,125 equivalent, key selection criteria include open-drain drive strength (–24 mA at 3.0 V), input overvoltage tolerance (5.5 V), IOFF-enabled system-level power sequencing, and –40 °C to +125 °C industrial temperature range.

Technical Context

This device integrates three independent inverters, each with an open-drain output stage enabling wired-AND configurations and bidirectional voltage translation. Input Schmitt triggers provide hysteresis (typically 0.3 V at VCC = 3.3 V), supporting slow-rising signals from microcontrollers or sensors.

The IOFF circuit actively disables outputs when VCC = 0 V, blocking backflow current during hot-swap or partial power-down sequences. All inputs tolerate up to 5.5 V regardless of VCC, allowing direct connection to 5 V sources while powered from 1.65–3.3 V rails.

FAQ

Can 74LVC3G06GD,125 be used as a standalone level shifter between 1.8 V and 5 V domains?

No. While inputs tolerate 5.5 V, the output high level is defined only by the external pull-up voltage-not internally generated. To translate from 1.8 V logic to 5 V signals, the pull-up must be connected to 5 V, and the driven load must be compatible with open-drain operation and appropriate rise time. The device does not provide active high-side drive.

What is the maximum capacitive load each output can drive at 3.3 V supply while maintaining 10 ns propagation delay?

At VCC = 3.3 V, tPD ≤ 4.3 ns (max) is specified for CL = 50 pF per output. Driving >50 pF increases delay nonlinearly due to RC time constant; for 10 ns worst-case, total load (including trace and probe capacitance) must remain ≤35 pF with 500 Ω termination per the test circuit in Figure 5.

Does the IOFF feature disable all three outputs simultaneously when VCC drops to 0 V?

Yes. IOFF is a global circuit that disconnects all three output FETs from both internal logic and the output terminals when VCC falls below ~0.2 V. This prevents any back-current path through the outputs, regardless of input or output pin voltages, satisfying JEDEC JESD78 latch-up immunity requirements.

Is the Schmitt-trigger hysteresis value fixed or supply-dependent?

Hysteresis is supply-dependent: typical ΔVIH–VIL = 0.3 V at VCC = 3.3 V, scaling approximately linearly to ~0.2 V at 1.8 V and ~0.4 V at 5.0 V. This ensures consistent noise margin across the full 1.65–5.5 V operating range without requiring external hysteresis components.
