TXB0104QPWRQ1

Overview

The TXB0104QPWRQ1 is an automotive-grade, 4-bit bidirectional voltage-level translator manufactured by Texas Instruments. It utilizes two independent configurable power rails to facilitate translation between different voltage nodes. The device supports a VCCA range of 1.2V to 3.6V and a VCCB range of 1.65V to 5.5V, ensuring VCCA does not exceed VCCB. It operates within a temperature range of -40°C to +125°C and features a propagation delay of 7.7ns with a data rate of 100Mb/s. The component is housed in a 14-pin PowerPAD™ TSSOP package.

Feature Summary

• Automotive qualification compliant with AEC-Q100 standards for robust performance in vehicle environments.
• Automatic direction sensing eliminates the need for directional control signals, simplifying interface design.
• Supports partial power-down mode via Ioff circuitry to prevent excessive current draw during power-off states.
• Provides high electrostatic discharge protection exceeding JESD 22 standards for enhanced signal integrity.

Applications

• Automotive infotainment systems requiring secure data exchange between low-voltage processors and higher-voltage peripherals.
• Body control modules interfacing sensors and actuators operating at varying logic levels.
• Telematics units connecting communication interfaces across different voltage domains.

Procurement Notes

Verify that the specific suffix QPWRQ1 corresponds to the intended automotive grade and tape-and-reel packaging configuration. Confirm that the manufacturer's datasheet explicitly lists this part number under the TXB0104-Q1 family. Ensure compatibility with the target PCB footprint for the 14-pin TSSOP package before finalizing procurement specifications.

Selection Notes

Select this component when designing circuits that require automatic bidirectional level shifting in automotive applications. It is suitable for bridging logic families where VCCA ranges from 1.2V to 3.6V and VCCB ranges from 1.65V to 5.5V. Choose this part over non-automotive variants if AEC-Q100 reliability and extended temperature operation are mandatory requirements for the system.

Part Context

This device belongs to the Texas Instruments TXB0104-Q1 family of voltage-level translators. It shares functional similarities with other members of the series but is distinguished by its automotive qualification and specific package variant. The product line focuses on providing reliable, low-power translation solutions for complex electronic architectures.

Replacement Considerations

Direct substitutes include other AEC-Q100 qualified versions within the TXB0104 family, such as TXB0104PWPRQ1 or TXB0104PWRQ1, provided the pinout and electrical characteristics remain identical. Verify package dimensions and thermal performance when swapping between different suffixes.
