Overview
The TXS0102VQDCURQ1 is an automotive-grade, two-bit bidirectional voltage-level translator designed for open-drain and push-pull applications. It operates with VCCA ranging from 1.65V to 3.6V and VCCB from 2.3V to 5.5V. The device supports maximum data rates of 24 Mbps in push-pull mode and 2 Mbps in open-drain mode. It features integrated 10kΩ pull-up resistors, auto-direction sensing without control signals, and Ioff support for partial-power-down modes. Qualified under AEC-Q100 Grade 1, it functions within a temperature range of -40°C to +125°C.
Feature Summary
- Auto-direction sensing eliminates the need for external direction-control signals by automatically determining data flow between ports.
- Integrated 10kΩ pull-up resistors on both ports provide DC current sourcing capability, removing the requirement for external components in standard open-drain configurations.
- VCC isolation feature ensures all ports enter a high-impedance state if either power supply input is at ground potential.
- No power-supply sequencing is required, allowing either VCCA or VCCB to ramp up first without damaging the device.
Applications
- I2C / SMBus interfaces
- UART communication links
- General-purpose input/output (GPIO) translation
Procurement Notes
Verify that the specific ordering suffix matches the required package type and tape-and-reel specifications. Confirm the component meets AEC-Q100 Grade 1 requirements for the intended automotive environment. Ensure design parameters strictly adhere to the recommended operating conditions regarding VCCA and VCCB voltage limits.
Selection Notes
Select this component when interfacing mixed-voltage systems requiring bidirectional translation between 1.8V, 2.5V, 3.3V, and 5V nodes. It is suitable for designs needing auto-direction sensing and internal pull-ups. Verify that the application does not exceed the specified maximum data rates for the chosen driving mode.
Part Context
This part belongs to the Texas Instruments TXS0102-V family of automotive voltage translators. It utilizes a pass-gate architecture with edge-rate accelerators to enhance data throughput. The device is housed in an 8-pin VSSOP (NanoStar) package, providing a compact solution for space-constrained PCB layouts in automotive electronics.
Replacement Considerations
Consult official substitution lists for verified alternatives. Generic logic translators may lack the specific automotive qualification or integrated pull-up features required for direct replacement in this application.
