PCA9306-Q1 - SMBus Voltage-Level Translator

General Description

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

The PCA9306-Q1 allows bidirectional voltage translations between 1.2 V and 5 V, without the use of a direction pin.

Key Features

  • AEC-Q100 qualified for automotive.
