74LVC2G125DC,125

Overview

The Nexperia 74LVC2G125DC,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 supports input voltages up to 5.5 V. The device incorporates Schmitt-trigger action at all inputs for noise immunity and includes IOFF circuitry to prevent backflow current during partial power-down applications. It is housed in an 8-lead VSSOP package (SOT765-1) and is specified for operation from -40 °C to +125 °C.

Feature Summary

• Provides high noise immunity through Schmitt-trigger action at all inputs
• Supports partial power-down mode via integrated IOFF circuitry to disable outputs
• Enables direct interface with TTL levels and mixed 3.3 V/5 V environments

Applications

• Mixed 3.3 V and 5 V translation environments
• Partial power-down applications requiring backflow current prevention
• Bus buffering and line driving with three-state control

Procurement Notes

Verify the specific ordering suffix matches the required package type, as the base part number covers multiple packages. Confirm that the DC suffix corresponds to the VSSOP8 (SOT765-1) variant. Ensure compliance with RoHS and REACH standards if applicable to your manufacturing requirements. Check the latest datasheet revision for any updates to marking codes or pin configurations before finalizing procurement.

Selection Notes

Select this component when a dual buffer with three-state outputs and Schmitt-trigger inputs is required. It is suitable for designs needing tolerance to slower input rise and fall times. Consider the VSSOP8 package dimensions for PCB layout constraints. Verify that the operating temperature range meets the environmental specifications of the target application.

Part Context

This device belongs to the 74LVC family of low-voltage CMOS logic devices. It is functionally similar to other 74LVC2G125 variants but differs in packaging. Other available packages include TSSOP8, XSON8, and various XSON8 footprints. The DC suffix specifically denotes the VSSOP8 plastic very thin shrink small outline package.

Replacement Considerations

Direct replacements must match the 74LVC2G125 functionality and VSSOP8 package. Variants such as 74LVC2G125DP (TSSOP8) offer identical electrical performance but require different footprint considerations. Ensure any substitute maintains the same IOFF capability and Schmitt-trigger input characteristics.
