TXB0302DQMR

Translators, Level Shifters Overview

The TXB0302DQMR is a 2-bit bidirectional voltage-level translator manufactured by Texas Instruments. It features automatic direction sensing to manage signal flow between different voltage domains. The device supports supply voltages ranging from 0.8 V to 3.6 V on both the A and B ports, enabling flexible interface configurations. It operates within an industrial temperature range of -40°C to +85°C and is housed in a compact SOT-23 package.

Translators, Level Shifters Feature Summary

• Automatic direction sensing eliminates the need for direction control pins
• Bidirectional data transfer capability between two voltage domains
• Supports low-voltage operation down to 0.8 V

Translators, Level Shifters Applications

• Interfacing between low-voltage processors and higher-voltage peripherals
• Level shifting in mixed-voltage digital systems
• Portable devices requiring power-efficient voltage translation

Translators, Level Shifters Procurement Notes

Verify the specific suffix DQMR corresponds to the SOT-23 package and reel quantity requirements. Confirm RoHS compliance status and manufacturing date codes against current inventory standards. Ensure the operating voltage range matches the target system's logic levels before finalizing procurement orders.

Translators, Level Shifters Selection Notes

Select this component when bidirectional level translation is required without explicit direction control signals. It is suitable for applications where space is limited due to its small footprint. Ensure the input voltage does not exceed the maximum rating of 3.6 V on either port to prevent damage.

Translators, Level Shifters Part Context

This part belongs to the TXB03xx series of voltage translators from Texas Instruments. These devices are designed to simplify system design by removing the complexity of manual direction control. The series offers various bit widths and package options to suit different integration needs.

Translators, Level Shifters Replacement Considerations

The TXS0302 is a similar 2-bit bidirectional translator but lacks automatic direction sensing. Verify if manual direction control is acceptable for the application. Other family members like TXB0104 offer more bits but may require different pinout considerations.
