Nexperia USA Inc. 74LVC1G06GW,125

Overview

74LVC1G06GW,125 from Nexperia is a single CMOS inverter 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, ±24 mA sink capability at 3.0 V, and operates across -40 °C to +125 °C. It is used in I²C bus pull-up interfaces and mixed-voltage GPIO signal conditioning.

For engineers reviewing the 74LVC1G06GW,125 datasheet, 74LVC1G06GW,125 pinout, 74LVC1G06GW,125 application, or 74LVC1G06GW,125 equivalent, key selection criteria include open-drain drive strength, IOFF-enabled system-level power sequencing, Schmitt-trigger hysteresis for slow-edge signals, and TSSOP5 package compatibility with high-density PCB layouts.

Technical Context

The device implements a single inverting logic gate with an open-drain NMOS output stage, requiring an external pull-up resistor to define HIGH-level voltage. Its Schmitt-trigger input provides 0.3–0.4 V hysteresis (depending on VCC), enabling robust operation with slow-rising or noisy control signals such as push-button debouncing or sensor wake-up lines.

IOFF circuitry actively disables both input and output paths when VCC = 0 V, blocking backflow current up to ±50 mA and supporting hot-swap and partial-power-down architectures. The logic function follows standard inverter truth table: input LOW → output HIGH-impedance; input HIGH → output LOW (sinking).

FAQ

Can 74LVC1G06GW,125 drive an LED directly?

Yes - with appropriate current-limiting resistor. At VCC = 3.3 V and sink current ≤24 mA, it can drive standard 20 mA LEDs. Connect LED anode to VCC (3.3 V or 5 V), cathode to Y pin, and size resistor to set forward current. Do not exceed 24 mA absolute maximum to avoid VOL degradation or thermal stress.

Is the open-drain output compatible with I²C Fast Mode (400 kHz)?

Yes - with proper pull-up selection. Using a 2.2 kΩ resistor to 3.3 V yields ~300 ns rise time (calculated from CPD = 14 pF and CL ≈ 20 pF), well within I²C Fast Mode timing budget. Ensure total bus capacitance stays ≤400 pF; the device's 1.7 ns propagation delay adds negligible latency.

What happens to the output when VCC = 0 V and input is HIGH?

The IOFF circuit disables the output NMOS, forcing Y into high-impedance state regardless of input voltage. Output leakage remains ≤±2 μA, preventing backfeed into powered-down sections. This behavior is verified across -40 °C to +125 °C and is intrinsic to the silicon design - no external biasing required.

Does the Schmitt-trigger input affect propagation delay?

Yes - hysteresis adds ~0.3–0.5 ns to tpd versus non-Schmitt inverters at same VCC, due to dual-threshold switching. However, this is offset by improved noise margin: input can tolerate up to 1.2 Vpp of superimposed noise without false triggering, making it superior for noisy industrial environments despite minor delay penalty.
