SN74LV1T125DBVRG4

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LV1T125DBVRG4 is a single-supply, single-channel buffer gate featuring three-state outputs with an active-low enable. It operates within a voltage range of 1.6V to 5.5V and supports bidirectional translation between different logic levels. The device utilizes CMOS technology and offers overvoltage-tolerant inputs, allowing safe interfacing with higher voltage signals even when the supply voltage is lower. It provides push-pull output topology with fixed-direction control, ensuring signal integrity in low-voltage applications.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Bidirectional voltage level translation between different logic domains
• Bus-oriented driving for data lines and control signals
• Improving switching speed and drive capability for CMOS devices

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'G4' indicates RoHS compliance and manufacturing changes compared to standard versions. Confirm package type SOT-23-5 matches design requirements. Check current availability status as distributors may list discontinued or alternate variants. Ensure ordering information aligns with the exact datasheet revision for electrical characteristics.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a single-channel buffer with active-low enable is required for low-voltage systems. It is suitable for applications needing bidirectional level shifting between 1.6V and 5.5V domains. Consider the SOT-23-5 package for space-constrained designs. Verify input tolerance requirements match the target system voltages to ensure reliable operation without external protection.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the Texas Instruments SN74LV1T series of single-supply logic buffers. It is functionally similar to the SN74LV1T126 but differs in enable polarity, with the 125 using an active-low enable while the 126 uses active-high. Both share the same LV family characteristics, including wide voltage operation and overvoltage tolerance, making them interchangeable in designs where enable logic can be inverted.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

SN74LV1T125DBVR is the direct commercial equivalent without the G4 suffix. SN74LV1T126DBVR serves as a functional alternative if active-high enable logic is acceptable instead of active-low.
