Product Introduction

Overview

The PCA9306DCUTE4, produced by Texas Instruments, is a dual bidirectional I2C and SMBus voltage-level translator. This device is designed to facilitate seamless communication between devices operating at different voltage levels, making it an essential component in mixed-mode I2C applications. It features an enable (EN) input and operates without the need for a direction pin, allowing for bidirectional voltage translation between 1.2 V and 5.5 V. The PCA9306DCUTE4 is available in a VSSOP package, which enables convenient surface mount installation. It is capable of handling two buses with different operating frequencies, such as a 400-kHz bus and a 100-kHz bus, by isolating the slower bus during fast-mode communication using the EN pin.
