TXB0304RUTR

The TXB0304RUTR from Texas Instruments is a 4-bit, auto-direction sensing, bidirectional voltage level translator. It is designed to operate with supply voltages ranging from 0.9V to 3.6V on both the A and VCC ports, offering a fully symmetric voltage translation capability.

This device supports data rates up to 140 Mbps and features an auto-direction sensing mechanism, eliminating the need for explicit direction control pins. Key features include an edge rate accelerator, integrated pull-up resistors, output enable functionality, and partial power-down mode (Ioff) for reduced power consumption. The low supply current is typically 0.01 mA, with a maximum of 5 µA in low power mode.

Designed for surface mounting, the TXB0304RUTR is available in a compact 12-UQFN package measuring 1.7mm x 2mm. It operates within an ambient temperature range of -40°C to 85°C. The translator type is specifically for voltage level translation, with bidirectional channels and tri-state, non-inverted outputs. ESD protection exceeds JESD 22 standards, and latch-up performance is robust, exceeding 100 mA per JESD 78, Class II.

Applications for this translator include SPIO interfaces and general-purpose level shifting in systems requiring flexible voltage domain compatibility. Its symmetric supply voltage range and automatic direction detection make it suitable for various embedded systems and interface designs.
