TXS0108EQPWRQ1

Overview

The TXS0108EQPWRQ1 is an automotive-grade, eight-channel bidirectional voltage-level translator manufactured by Texas Instruments. It operates with a VCCA supply range of 1.4 V to 3.6 V and a VCCB supply range of 1.65 V to 5.5 V. The device supports data rates up to 110 Mbps and features automatic direction sensing for seamless signal translation between different voltage domains. It is housed in a 20-TSSOP package and complies with AEC-Q100 standards for automotive applications.

Feature Summary

• Supports bidirectional voltage translation between low-voltage (1.4V–3.6V) and high-voltage (1.65V–5.5V) logic domains
• Features automatic direction sensing to eliminate the need for external direction control pins
• Complies with AEC-Q100 qualification standards for automotive electronic components
• Provides open-drain and push-pull output configurations for flexible interface compatibility

Applications

• Automotive infotainment systems requiring communication between different voltage logic levels
• Interfacing microcontrollers with sensors or peripherals operating at varying supply voltages
• Bidirectional level shifting for I2C, SPI, and UART buses in automotive environments
• Connecting 1.8V or 3.3V logic devices to 5V legacy interfaces in vehicle electronics

Procurement Notes

Verify that the specific suffix 'QPWR' corresponds to the 20-TSSOP package variant when sourcing. Confirm AEC-Q100 compliance requirements match your system's reliability standards. Ensure voltage rails on both sides remain within the specified 1.4V–3.6V and 1.65V–5.5V limits during operation. Check for RoHS3 compliance if environmental regulations apply to your manufacturing process.

Selection Notes

Select this component when bidirectional translation is required without complex direction control logic. It is suitable for designs needing support for both open-drain and push-pull outputs. Consider this part for automotive projects demanding AEC-Q100 certification. Ensure the target application does not exceed the 110 Mbps data rate specification for reliable signal integrity across the translated channels.

Part Context

This device belongs to the TXS0108E family of voltage translators designed for automotive use. It shares functional similarities with other bidirectional translators but is specifically qualified for harsh automotive environments. The QPWR suffix indicates the TSSOP-20 packaging option, distinguishing it from other package variants like DGSR or PWRQ1 within the same logical family.

Replacement Considerations

Check for direct pin-compatible alternatives within the same Texas Instruments family that may offer different package options. Verify that any substitute maintains AEC-Q100 qualification if automotive reliability is mandatory. Ensure replacement parts support the same voltage ranges and data rates to avoid signal integrity issues.
