TXS0104EQWBQARQ1

Overview

The TXS0104EQWBQARQ1 is an automotive-grade, 4-bit 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 driving and 2 Mbps for open-drain driving. It features integrated 10-kΩ pullup resistors on all channels, eliminating the need for external components. The unit utilizes a WQFN-14 package and functions within an ambient operating temperature range of -40°C to +125°C.

Feature Summary

• Eliminates direction-control signals through automatic detection of data flow direction between ports.
• Integrates internal 10-kΩ pullup resistors on each channel to support open-drain configurations without external components.
• Supports mixed output types, allowing individual channels to be configured as either open-drain or push-pull.
• Provides high electrostatic discharge protection exceeding JESD 22 standards on both A and B ports.

Applications

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

Procurement Notes

Verify that the specific ordering suffix matches the required package type, as the TXS0104E-Q1 family includes multiple physical form factors such as TSSOP, WQFN, and UQFN. Confirm that the application environment strictly adheres to the recommended operating conditions regarding supply voltage limits and thermal constraints. Ensure compatibility with the target logic families before finalizing procurement specifications.

Selection Notes

Select this component when interfacing between incompatible logic chips requiring voltage mismatch bridging without host intervention. It is suitable for designs needing mixed open-drain and push-pull outputs on the same bus. Consider the specific package dimensions and thermal resistance characteristics relative to the PCB layout requirements. Verify that the system power sequencing does not violate the absolute maximum ratings during startup.

Part Context

This part belongs to the Texas Instruments TXS0104E-Q1 family of automotive voltage translators. It is specifically engineered for robust operation in harsh automotive environments, meeting AEC-Q100 qualification standards. The device serves as a bridge for communication protocols where voltage levels differ between the main processor and connected peripherals.

FAQ

Does the TXS0104EQWBQARQ1 require a direction control signal?

No, the device is a directionless translator that automatically detects the direction of data flow between the A and B ports without requiring a control signal.

What is the function of the OE pin?

The OE (Output Enable) pin controls the state of the outputs. Pulling the OE pin low places all outputs into a high-impedance state.

Can the device handle mixed data flows?

Yes, each channel can be mixed and matched with different output types and mixed data flows (transmit or receive) without host intervention.
