introduction

This is a breakout board for the PCA9306 dual bidirectional voltage-level translator.

Because different parts sometimes use different voltage levels to communicate, 

voltage level translators can be the key to making different parts play nice.

Features

• „ 2-bit bidirectional translator for SDA and SCL lines in mixed-mode I2C-bus applications

„* Standard-mode, Fast-mode, and Fast-mode Plus I2C-bus and SMBus compatible

• „ Less than 1.5 ns maximum propagation delay to accommodate Standard-mode and Fast-mode I2C-bus devices and multiple masters
• „ Allows voltage level translation between:
• ‹ 1.0 V Vref(1) and 1.8 V, 2.5 V, 3.3 V or 5 V Vbias(ref)(2)

‹* 1.2 V Vref(1)and 1.8 V, 2.5 V, 3.3 V or 5 V Vbias(ref)(2) ‹* 1.8 V Vref(1)and 3.3 V or 5 V Vbias(ref)(2)

• ‹ 2.5 V Vref(1) and 5 V Vbias(ref)(2)

‹* 3.3 V Vref(1) and 5 V Vbias(ref)(2)

• „ Provides bidirectional voltage translation with no direction pin
• „ Low 3.5 Ω ON-state connection between input and output ports provides less signal distortion
