74LVC2G125DP,125

Overview

The Nexperia 74LVC2G125DP,125 is a dual bus buffer and line driver featuring three-state outputs controlled by active-low output enable inputs (nOE). It operates within a supply voltage range of 1.65 V to 5.5 V and utilizes Schmitt-trigger inputs for noise immunity. The device includes IOFF circuitry to prevent backflow current during partial power-down states. It supports an output drive of ±24 mA at 3.0 V and provides ESD protection exceeding 2000 V (HBM) and 1000 V (CDM. Packaged in TSSOP8 (SOT505-2), it functions from -40 °C to +125 °C.

Feature Summary

• Three-state outputs controlled by active-low nOE inputs
• IOFF circuitry prevents damaging backflow current during power-down
• Schmitt-trigger inputs provide tolerance for slow rise and fall times
• Overvoltage tolerant inputs up to 5.5 V

Applications

• Translating signals between mixed 3.3 V and 5 V logic environments
• Driving high-capacitance or transmission-line loads on buses
• Partial power-down mode applications requiring isolation

Procurement Notes

Verify the specific ordering suffix matches the required package type, as the base part number covers multiple variants. Confirm that the temperature grade corresponds to the application's thermal requirements. Ensure the design accounts for the specified latch-up performance limits and absolute maximum ratings to prevent device stress.

Selection Notes

Select this component when bidirectional buffering with defined high-impedance states is required. The wide supply range allows compatibility with various logic families. Verify that the input transition rates remain within the specified limits for the chosen operating voltage to ensure correct Schmitt-trigger operation and signal integrity.

Part Context

This device belongs to the 74LVC family of low-voltage CMOS logic components manufactured by Nexperia. It serves as a specialized buffer variant within the broader 74-series logic ecosystem, designed specifically for interface bridging and signal conditioning in modern digital systems where voltage level translation and bus isolation are critical.

Replacement Considerations

Direct replacements include other 74LVC2G125 variants such as 74LVC2G125DC, 74LVC2G125GT, 74LVC2G125GN, and 74LVC2G125GS, provided the package footprint and pinout are compatible with the existing PCB layout.
