TXU0204QWBQARQ1

Overview

The TXU0204QWBQARQ1 is an automotive-grade, 4-bit fixed-direction voltage-level translator with Schmitt-trigger inputs and 3-state outputs. It features a fully configurable dual-rail design supporting supply voltages from 1.1V to 5.5V on both ports. The device supports data rates up to 200Mbps for 3.3V to 5.0V translations. It includes VCC isolation and Ioff-float capabilities for partial-power-down modes. Operating temperatures range from -40°C to +125°C.

Feature Summary

• Schmitt-trigger inputs handle slow and noisy signals while preventing channel floating via integrated static pull-down resistors.
• Dual-supply architecture allows independent A and B port voltage configurations within the 1.1V to 5.5V range.
• Ioff-float feature disables all outputs when either supply drops below 100mV or disconnects, ensuring high-impedance states.

Applications

• Eliminating slow or noisy input signals in digital circuits
• Driving indicator LEDs or buzzers with high drive strength
• Debouncing mechanical switches
• General purpose I/O level shifting between different logic families
• Push-pull level shifting for UART, SPI, and JTAG interfaces

Procurement Notes

Verify that the specific ordering suffix matches the required WBQA wettable flank QFN package configuration. Confirm the component meets AEC-Q100 qualification standards for automotive applications. Ensure the selected variant aligns with the necessary thermal and electrical specifications for the target operating environment.

Selection Notes

Select this component for applications requiring fixed-direction translation with high drive strength capabilities. The device is suitable where pinout compatibility with the TXB family is needed but higher output current is required. Consider the dual-rail flexibility for systems connecting disparate voltage domains without inversion.

Part Context

This part belongs to the TXU0x04-Q1 family of automotive 4-bit unidirectional voltage-level translators. It shares pinout compatibility with the TXB0104-Q1 but offers enhanced drive strength for specific load requirements. The family includes variants like TXU0104-Q1 and TXU0304-Q1 for different directional configurations.
