TXU0104RUTR Bidirectional level shifter, voltage translator IC Detailed Overview
The TXU0104RUTR is a 4-bit bidirectional voltage-level translator from Texas Instruments, designed for asynchronous communication between mixed-voltage systems. This compact IC operates with 1.2V to 3.6V on the A port and 1.65V to 5.5V on the B port, enabling seamless voltage translation across different logic families. Packaged in a tiny 12-pin UQFN (RUT) measuring just 1.8mm × 1.6mm, it features automatic direction sensing that eliminates the need for direction control pins, simplifying system design.
Texas Instruments logic translator Key Features
The TXU0104RUTR boasts 100Mbps maximum data rate performance with push-pull outputs that eliminate the need for external pull-up resistors. Its partial power-down (Ioff) protection prevents current backflow when powered off, while 24mA output drive strength ensures robust signal integrity. The translator requires no power sequencing between VCCA and VCCB, offering true power-up/down glitch protection. Unique edge-rate acceleration circuitry minimizes propagation delay while maintaining signal quality, making it particularly effective for high-speed interfaces.
TXU0104RUTR Applications
This voltage-level translator is ideal for I²C, SPI, and UART interfaces in mixed-voltage systems. It's widely used in smartphones, tablets, and wearable devices for bridging processors with peripheral components. Industrial applications include sensor interfaces, factory automation equipment, and IoT edge nodes. The device also serves well in automotive infotainment systems, medical monitoring devices, and battery management systems where reliable voltage translation is critical.
TXU0104RUTR I²C level shifter Selection Advantages
The TXU0104RUTR offers superior integration compared to discrete solutions, combining four channels in an ultra-compact footprint. Its bidirectional capability reduces component count by 50% versus unidirectional translators. The auto-direction sensing feature simplifies firmware development by eliminating control logic. With 1.5ns typical propagation delay, it outperforms similar devices in speed-critical applications. The 1.2V to 5.5V wide voltage range supports virtually all modern logic standards without requiring additional components.
