TXB0104QRGYRQ1

Overview

The TXB0104QRGYRQ1 is an automotive-grade, four-channel bidirectional voltage-level translator manufactured by Texas Instruments. It operates with a VCCA supply range of 1.2 V to 3.6 V and a VCCB range of 1.65 V to 5.5 V. The device supports data rates up to 100 Mbps and features automatic direction sensing. It is housed in a 14-pin VQFN package (3.5x3.5 mm) and meets AEC-Q100 qualification standards for operation across a temperature range of -40°C to +125°C.

Feature Summary

• Automatic direction sensing eliminates the need for external direction control signals
• Supports bidirectional translation between low-voltage and high-voltage logic domains
• Qualified for automotive applications under AEC-Q100 standards

Applications

• Automotive infotainment systems requiring mixed-voltage interface translation
• Body control modules connecting sensors and actuators
• Gateway devices bridging different voltage logic levels in vehicle networks

Procurement Notes

Verify that the specific suffix 'Q1' confirms AEC-Q100 automotive qualification status. Ensure the ordering part number matches the required VQFN-14 package variant. Confirm that the manufacturer's datasheet specifies the exact electrical characteristics for your target operating conditions before finalizing procurement specifications.

Selection Notes

Select this component when designing automotive circuits requiring robust voltage translation between 1.2V and 5.5V domains. The integrated direction sensing simplifies PCB layout by removing control pins. Verify that the 100 Mbps speed capability aligns with the highest frequency signals present in the application bus.

Part Context

This device belongs to the Texas Instruments TXB0104 family of voltage translators. The 'Q1' suffix denotes automotive grade qualification, distinguishing it from commercial variants. It provides a compact solution for interfacing modern low-power microcontrollers with higher-voltage peripherals in space-constrained automotive enclosures.

Replacement Considerations

Check for direct pin-compatible alternatives within the same TXB0104 family that may offer different package options or updated revision statuses. Verify that any substitute maintains the same AEC-Q100 certification if automotive reliability is mandatory.
