TCA39306DTMR TI Voltage-Level Translator | 8-X2SON (1.35×0.8) | 2-bit, 0.9-5.5V

Product Overview

The TCA39306DTMR from Texas Instruments is a 2-bit bidirectional voltage-level translator designed for I²C and SMBus applications. It operates over a wide voltage range from 0.9V to 5.5V on both the VREF1 and VREF2 sides, making it ideal for multi-voltage systems. Housed in a compact 8-X2SON (1.35mm × 0.8mm) package, it provides automatic direction sensing without the need for a direction control pin, simplifying PCB layout and reducing BOM count.
