74LVC2G125GT,115

Overview

The Nexperia 74LVC2G125GT,115 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 incorporates IOFF circuitry to prevent backflow current during partial power-down states. Packaged in an XSON8 format with dimensions of 1 mm x 1.95 mm x 0.5 mm, it supports low-power CMOS consumption and direct interfacing with TTL levels.

Feature Summary

• Features IOFF circuitry that disables outputs to prevent damaging backflow currents when the device is powered down.
• Incorporates Schmitt-trigger action at all inputs to provide tolerance against slower input rise and fall times.
• Allows direct interface with TTL levels and accepts inputs driven from either 3.3 V or 5 V devices.

Applications

• Partial power-down applications requiring protection against backflow current
• Mixed 3.3 V and 5 V environments acting as translators
• Bus buffering and line driving operations

Procurement Notes

Verify the specific ordering suffix GT,115 corresponds to the XSON8 package variant SOT833-1. Confirm the temperature range specification matches the required operational environment limits. Ensure compatibility with the intended PCB footprint dimensions and terminal layout before finalizing procurement orders.

Selection Notes

Select this component for designs requiring dual-channel buffering with high noise immunity and partial power-down capabilities. The wide supply voltage range accommodates various logic families. Verify that the XSON8 package dimensions fit the available board space constraints and thermal dissipation requirements for the specific application load.

Part Context

This part belongs to the 74LVC2G125 family of dual bus buffers. The 'GT' designation specifically identifies the XSON8 leadless package type. Other variants in the series include TSSOP8 and VSSOP8 packages, offering flexibility for different spatial and manufacturing requirements while maintaining identical electrical characteristics.

Replacement Considerations

Direct substitutes include other 74LVC2G125 variants such as 74LVC2G125DP (TSSOP8) or 74LVC2G125DC (VSSOP8), provided the package form factor change is acceptable for the design.
