TXU0204QPWRQ1

Overview

The TXU0204QPWRQ1 is an automotive-grade, 4-bit dual-supply noninverting voltage level translator manufactured by Texas Instruments. It operates within a -40°C to +125°C ambient temperature range and features a fixed direction configuration where pins are referenced to the VCCA logic level. The device supports an output enable (OE) pin for control. It is housed in a 14-TSSOP package with a width of 4.40mm. The component is AEC-Q100 qualified for automotive applications and complies with RoHS3 standards.

Feature Summary

• Dual-supply architecture enabling translation between different voltage domains
• Fixed direction logic referencing inputs to the VCCA supply rail
• Automotive qualification ensuring reliability under extended temperature conditions
• Output enable functionality for power management and bus isolation

Applications

• Automotive infotainment system interconnects
• Body control module signal translation
• Dashboard display interface bridging
• Sensor data acquisition systems requiring voltage domain separation

Procurement Notes

Verify the specific suffix 'Q1' confirms automotive grade status and AEC-Q100 certification. Confirm the 'PWR' suffix indicates the 14-TSSOP package variant. Ensure the design accounts for the fixed direction constraint where all inputs reference VCCA. Validate that the target application does not require bidirectional auto-detection, as this model uses a fixed direction scheme.

Selection Notes

Select this component when a fixed-direction translation from a lower voltage domain (VCCA) to a higher voltage domain (VCCB) is required in automotive environments. It is suitable for applications needing four parallel channels without the complexity of bidirectional auto-direction detection. Consider alternative models if bidirectional communication or single-supply operation is necessary.

Part Context

This part belongs to the Texas Instruments TXU02xx series of voltage level translators. It is specifically designed for automotive electronics, distinguishing it from commercial variants through its extended temperature rating and robust qualification. The Q1 suffix denotes automotive grade, while PWR specifies the surface-mount TSSOP packaging.

Replacement Considerations

Public confirmed substitute: LSF0204QPWRQ1. Note that the LSF0204QPWRQ1 offers bidirectional auto-direction detection, whereas the TXU0204QPWRQ1 has fixed direction. Verify if the fixed direction constraint of the TXU0204QPWRQ1 is acceptable or if the bidirectional capability of the LSF0204QPWRQ1 provides necessary flexibility.
