SN74LV1T125DCKRG4

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LV1T125DCKRG4 is a single-buffer, non-inverting logic level shifter from Texas Instruments' LV1T family. It operates on a single power supply ranging from 1.6V to 5.5V and features push-pull outputs with three-state capability controlled by an active-low enable pin. The device supports bidirectional voltage translation between different logic domains while maintaining signal integrity. Packaged in a compact SC-70-5 (SOT-353) surface-mount footprint, it is designed for space-constrained applications requiring robust signal buffering and level shifting across wide voltage ranges.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Provides non-inverting buffering with three-state output control via an active-low enable input
• Supports bidirectional voltage translation between 1.6V and 5.5V logic domains
• Features overvoltage-tolerant inputs allowing safe operation with signals exceeding VCC
• Delivers high-speed performance suitable for data rates up to 150 Mbps

Buffers, Drivers, Receivers, Transceivers Applications

• GPIO expansion and signal buffering in mobile devices
• Level shifting between microcontrollers and peripheral sensors
• Bus driver applications in industrial control systems
• Signal conditioning in automotive electronic modules

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the G4 suffix indicates lead-free composition and RoHS compliance per Texas Instruments standards. Confirm the DCKR package variant matches the required SC-70-5 footprint dimensions. Ensure the catalog rating aligns with industrial or commercial temperature requirements. Cross-reference the specific revision of the datasheet to confirm pinout consistency with existing designs.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a single-channel buffer with independent enable control is required. Choose the LV1T125 over the LV1T126 if active-low enable logic is preferred. Consider the SC-70-5 package for minimal board area consumption compared to larger packages. Verify that the 1.6V minimum supply voltage meets the lowest system rail requirement.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LV1Txx series of single-supply logic level shifters. It shares the LV1T technology family characteristics with other members like the SN74LV1T34 and SN74LV1T86. The device complements the broader 74LV logic portfolio by offering low-voltage operation in ultra-small packages. It is functionally similar to the SN74AHCT1G125 but optimized for lower supply voltages.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The SN74LV1T125DCKR is the direct equivalent without the G4 suffix. Automotive-grade alternatives include the SN74LV1T125-Q1. For non-inverting buffers without enable pins, consider the SN74LV1T34. Check pin compatibility before substituting with generic equivalents.
