74LVC2G125DC-Q100125

Overview

The 74LVC2G125DC-Q100 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 supports an input voltage up to 5.5 V, enabling translation between mixed 3.3 V and 5 V logic environments. The device incorporates Schmitt-trigger action for tolerance to slow input transitions and includes IOFF circuitry to prevent backflow current during partial power-down states. Qualified to AEC-Q100 Grade 1 standards, it functions reliably from -40 °C to +125 °C.

Feature Summary

• Automotive qualification in accordance with AEC-Q100 Grade 1 standard
• IOFF circuitry enables partial power-down mode operation
• Schmitt-trigger inputs provide tolerance for slower rise and fall times
• Overvoltage tolerant inputs allow direct interfacing with 5 V devices

Applications

• Mixed 3.3 V and 5 V logic level translation
• Partial power-down applications requiring backflow prevention
• Automotive electronic systems

Procurement Notes

Verify the specific package variant against the ordering information table. The DC suffix corresponds to the VSSOP8 plastic very thin shrink small outline package (SOT765-1). Confirm that the required temperature range matches the specified -40 °C to +125 °C operating conditions before finalizing procurement specifications.

Selection Notes

Select this component when a dual buffer with three-state control is required for automotive or industrial environments. Ensure the design accommodates the wide supply voltage range and utilizes the Schmitt-trigger inputs if signal edges are slow. Verify that the VSSOP8 package dimensions fit the available PCB space and thermal requirements.

Part Context

This part belongs to the Nexperia 74LVC2G125-Q100 family of dual bus buffers. It shares functional characteristics with other members of the series but is distinguished by its specific VSSOP8 packaging and automotive-grade qualification. The product data sheet defines its electrical limits, pin configurations, and dynamic performance metrics.

Replacement Considerations

The 74LVC2G125DP-Q100 serves as a direct substitute, offering identical functionality but housed in a TSSOP8 package instead of the VSSOP8 configuration.
