SN74LV1T34QDBVRQ1

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LV1T34QDBVRQ1 is an automotive-grade single buffer logic level shifter from Texas Instruments. It operates on a single supply voltage ranging from 1.6 V to 5.5 V. The device supports up-translation from lower voltages such as 1.2 V, 1.5 V, and 1.8 V to higher levels like 2.5 V, 3.3 V, and 5.0 V. It also facilitates down-translation from 5.0 V, 3.3 V, and 2.5 V inputs to 1.8 V or 2.5 V outputs. The component features 5.5 V tolerant input pins and achieves data rates up to 150 Mbps when powered by 5 V or 3.3 V supplies.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix matches the required package type, as the Q1 designation indicates automotive qualification. Confirm that the DBVR suffix corresponds to the SOT-23-5 package variant needed for the design. Ensure compliance with AEC-Q100 standards if the application requires automotive reliability specifications. Check datasheet revision history for any updates to electrical characteristics before finalizing procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a single-channel buffer with bidirectional level translation capabilities is required. It is suitable for interfacing low-voltage sources with higher-voltage loads or vice versa. Consider the 5.5 V tolerant inputs for systems where signal levels may exceed the supply voltage. Evaluate thermal performance and load capacitance requirements against the absolute maximum ratings to ensure reliable operation under all expected conditions.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LV1T34-Q1 family of single power supply buffers. It shares functional similarities with other LVxT enhanced input voltage devices but is specifically qualified for automotive environments.
