TXS0104EQRUTRQ1

Overview

The TXS0104EQRUTRQ1 is an automotive-grade, four-channel bidirectional voltage-level translator designed for open-drain and push-pull applications. It operates with a VCCA range of 1.65 V to 3.6 V and a VCCB range of 2.3 V to 5.5 V. The device supports maximum data rates of 24 Mbps for push-pull configurations and 2 Mbps for open-drain setups. It features integrated 10-kΩ pullup resistors, eliminating the need for external components. The component utilizes a pass-gate architecture with edge-rate accelerators and requires no direction-control signal.

Feature Summary

• Eliminates the requirement for a direction-control signal through automatic detection of data flow direction between ports.
• Integrates internal 10-kΩ pullup resistors on both A and B ports to support open-drain logic without external components.
• Provides high electrostatic discharge protection exceeding JESD 22 standards for both human-body and charged-device models.
• Supports mixed output types and data flows across channels without host intervention.

Applications

• Automotive infotainment systems
• Advanced driver assistance systems (ADAS)
• I2C or 1-wire voltage-level translation
• Isolating and translating signals between main processors and peripheral modules

Procurement Notes

Verify that the specific ordering suffix matches the required package type, as the TXS0104E-Q1 family includes multiple physical packages such as TSSOP-14, WQFN-14, and UQFN-12. Confirm that the selected variant meets the necessary thermal resistance requirements for your specific PCB layout. Ensure the supply voltages applied to VCCA and VCCB strictly adhere to the recommended operating conditions where VCCA must not exceed VCCB.

Selection Notes

Select this component when interfacing logic families with incompatible voltage levels in automotive environments. It is suitable for bridging gaps between low-voltage nodes like 1.8 V and higher nodes like 3.3 V or 5 V. Choose this part if the application demands auto-direction sensing and does not require external pullup resistors. Verify that the maximum data rate requirements align with either the push-pull or open-drain specifications provided in the datasheet.

Part Context

This device belongs to the Texas Instruments TXS0104E-Q1 family of automotive voltage-level translators. It is specifically engineered for robust performance in harsh automotive environments, meeting AEC-Q100 qualification standards. The family offers various package options to accommodate different board space constraints while maintaining consistent electrical characteristics for bidirectional level shifting.

Replacement Considerations

Direct replacements within the same family include TXS0104EQARQ1 and TXS0104EBQAQ1, which share identical electrical specifications but differ in physical package dimensions. When substituting, ensure the pinout compatibility matches the target footprint, particularly regarding the OE pin and ground connections.
