PCA9306 - SMBus Voltage-Level Translator

General Description

The PCA9306 device is a dual bidirectional I2C and SMBus voltage-level translator with an enable (EN) input, and is operational from 1.2-V to 3.3-V VREF1 and 1.8-V to 5.5-V VREF2.

The PCA9306 device allows bidirectional voltage translations between 1.2 V and 5 V, without the use of a direction pin.

Key Features

  • 1 2-Bit bidirectional translator for SDA and SCL lines in mixed-mode I2C.
