PCA9306DCUR | Bidirectional I²C Level Translator | 1.0V–5.5V Logic Level Shifter | Texas Instruments (TI)

Product Overview

     The PCA9306DCUR from Texas Instruments is a dual bidirectional voltage-level translator designed for I²C and SMBus communication between devices operating at different voltage levels.
     It uses an open-drain architecture with automatic direction sensing and supports level shifting between 1.0V and 5.5V.
     The device ensures minimal propagation delay and low leakage for reliable data transfer in mixed-voltage environments.
     Packaged in a compact VSSOP-8 (DCU), it is ideal for space-constrained and power-sensitive applications.
