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
