SN74LV1T34DCKR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LV1T34DCKR is a single power supply buffer gate and CMOS logic level shifter manufactured by Texas Instruments. It operates within a voltage range of 1.6 V to 5.5 V and features a propagation delay of 3 ns. The device utilizes an SC-70 (SOT-353) surface-mount package with five pins. It supports a wide operating temperature range from -40°C to +125°C and includes three-state output capability for bus holding.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Provides unidirectional voltage translation between different logic families using a single power supply.
• Features three-state outputs to prevent bus contention in parallel data transmission environments.
• CMOS construction ensures low static power consumption and high noise immunity across the operating voltage range.

Buffers, Drivers, Receivers, Transceivers Applications

• Bidirectional voltage translation between 1.8 V, 2.5 V, 3.3 V, and 5 V logic domains.
• Post-drive buffering for microcontrollers and field-programmable gate arrays.
• Bus holding applications in multi-drop communication systems.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix DCKR corresponds to the SC-70-5 package configuration required for your layout. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the ordering part number matches the exact tape-and-reel quantity specifications defined in the latest datasheet revision to avoid packaging discrepancies during assembly.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a single-channel non-inverting buffer with voltage shifting capability is required in space-constrained designs. The LV series offers superior performance over standard LVC variants at lower voltages. Verify that the input signal levels fall within the specified common-mode range relative to the selected supply voltage to ensure correct logical operation.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the SN74LV1T34 family of single-buffer logic level shifters. It shares functional similarities with other members like the SN74LV1T34DCKRG4, differing primarily in manufacturing lot codes or environmental compliance markings rather than electrical characteristics. The SC-70 package allows for compact PCB footprint optimization compared to larger leaded packages.
