NXP Semiconductors 74LVC3G06DP,125

Overview

74LVC3G06DP,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 pull-up control, GPIO signal inversion, and mixed-voltage interface bridging.

For engineers reviewing the 74LVC3G06DP,125 datasheet, 74LVC3G06DP,125 pinout, 74LVC3G06DP,125 application, or 74LVC3G06DP,125 equivalent, key selection criteria include open-drain drive capability (–24 mA at 3.0 V), –40 °C to +125 °C temperature range, TSSOP8 package compatibility, and IOFF-enabled system-level power sequencing.

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), tolerating slow-rising signals and improving noise margin in noisy environments.

The IOFF circuit actively disables outputs when VCC = 0 V, blocking backflow current up to ±2 μA, making it suitable for hot-swap and partial-power-down systems. All inputs tolerate up to 5.5 V regardless of VCC, supporting direct interfacing with 5 V TTL and CMOS sources.

FAQ

Can the 74LVC3G06DP,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 wide 1.65 V–5.5 V supply range allows configuration with VCC = 1.8 V while driving 5 V pull-ups. The open-drain outputs ensure safe bidirectional translation without DC current flow between domains.

What is the maximum sink current per output at 5 V supply?

At VCC = 4.5 V to 5.5 V, the device guarantees VOL ≤ 0.55 V with IO = 32 mA (per output). This is validated per Table 7 in the datasheet and supports robust pull-down for standard I²C bus loads and LED drivers.

Does the IOFF feature require external biasing or control signals?

No - IOFF activates automatically when VCC = 0 V. No external enable/disable pin or voltage threshold setting is needed. Output leakage remains ≤ ±2 μA, and internal circuitry blocks reverse current without auxiliary components.

How does the Schmitt-trigger input improve performance in noisy environments?

Schmitt-trigger inputs provide ~0.3 V hysteresis at VCC = 3.3 V, meaning VIH ≈ 2.0 V and VIL ≈ 1.7 V. This prevents multiple transitions on slow or noisy edges, eliminating contact bounce artifacts from switches and reducing EMI-induced glitches in motor-control feedback paths.
