Product Description

The PCA9306DP1 is a bidirectional I2C converter and dual voltage bus switch designed for level translation between two voltage domains. It features dual bidirectional voltage translation channels, supporting seamless communication across different voltage levels (VREF1: 1.0V to 3.3V, VREF2: 1.8V to 5.5V). This compact level translator operates across an industrial temperature range (-40°C to +85°C) and is ideal for interfacing mixed-voltage I2C/SMBus systems in applications like industrial automation, consumer electronics, and embedded systems. Its key advantages include automatic direction sensing, low propagation delay, and no external pull-up resistors required. However, it does not support hot-swapping and has a limited current drive capacity. The PCA9306DP1 eliminates bus contention risks while maintaining full I2C protocol integrity between bidirectional buses.
