TXS0104EQPWRQ1

Overview

The TXS0104EQPWRQ1 is an automotive-grade, 4-bit bidirectional voltage-level translator designed for open-drain applications. It operates with a VCCA range of 1.65V to 3.6V and a VCCB range of 2.3V to 5.5V, ensuring VCCA does not exceed VCCB. The device supports data rates up to 2 Mb/s for open-drain configurations and 24 Mb/s for push-pull setups. Propagation delays vary between 2.4 ns and 4.6 ns depending on the specific channel configuration. It functions within a temperature range of -40°C to +125°C and is housed in a 14-pin TSSOP package.

Feature Summary

• Provides bidirectional voltage translation between low-voltage A-port and higher-voltage B-port domains without requiring explicit direction control signals.
• Supports both open-drain and push-pull output configurations to accommodate various interface standards.
• Features automatic direction sensing to facilitate seamless signal transfer across different voltage levels.
• Complies with AEC-Q100 standards for automotive reliability and includes electrostatic discharge protection.

Applications

• Automotive infotainment systems connecting microcontrollers to peripheral devices
• Interfacing logic circuits operating at different voltage nodes such as 1.8V, 2.5V, 3.3V, and 5V
• Open-drain bus applications requiring level shifting in automotive environments

Procurement Notes

Verify that the component matches the exact Texas Instruments part number TXS0104EQPWRQ1, including the Q1 suffix which denotes automotive qualification. Confirm the package type is 14-TSSOP and check for RoHS compliance documentation. Ensure the supplier provides traceability records consistent with automotive supply chain requirements.

Selection Notes

Select this component when interfacing open-drain or push-pull buses between 1.65V-3.6V and 2.3V-5.5V domains in automotive systems. It is suitable for applications requiring bidirectional translation without direction control pins. Consider propagation delay specifications if timing constraints are critical for the specific bus protocol being implemented.

Part Context

This device belongs to the TXS0104E-Q1 family of voltage translators from Texas Instruments. It is specifically engineered for automotive catalog applications, distinguishing it from general-purpose industrial variants through its extended temperature range and robustness standards required for vehicle electronics.

Replacement Considerations

Direct substitutes include the non-automotive TXS0104EQPW or the standard TXS0104VQPWRQ1 if automotive qualification is not strictly required. Verify pin compatibility and electrical characteristics before swapping.
