SN74LV1T126DCKRG4

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LV1T126DCKRG4 is a single power supply buffer gate with three-state output from Texas Instruments. It operates within a voltage range of 1.6V to 5.5V and features an active-high enable input. The device provides non-inverting buffering for CMOS logic signals in the SC-70-5 package. It supports bidirectional level translation between different voltage domains while maintaining signal integrity.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Provides single-channel non-inverting buffering with three-state output capability controlled by an active-high enable pin.
• Supports bidirectional level translation between varying voltage domains across a wide supply range.
• Features robust input structures that tolerate voltages exceeding the supply rail, ensuring safe operation during mixed-voltage interfacing.

Buffers, Drivers, Receivers, Transceivers Applications

• Bidirectional level shifting between different voltage domains in portable devices
• Signal buffering on microcontroller buses and peripheral interfaces
• Voltage translation in automotive electronic control units

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'G4' indicates lead-free and RoHS compliance status as per manufacturer documentation. Confirm the SC-70-5 package dimensions match design constraints. Ensure the active-high enable logic aligns with system control requirements before finalizing procurement specifications.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a single-channel buffer with three-state output is required for space-constrained designs. It is suitable for applications needing bidirectional level translation between 1.6V and 5.5V domains. Consider the SC-70-5 package size for tight PCB layouts requiring minimal footprint.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LV1T series of single-supply logic level shifters and buffers. It shares functional similarities with the SN74LV1T125 but differs in enable polarity. The DCKR variant denotes the reel packaging format for surface-mount assembly.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

SN74LV1T125DCKRG4 offers identical electrical performance but utilizes an active-low enable pin instead of active-high. Verify enable logic compatibility before substitution. Other family members like SN74LV1T34 provide buffering without enable functionality.
