SparkFun Voltage-Level Translator Breakout - PCA9306

• SparkFun Voltage-Level Translator Breakout - PCA9306
• Features a dual bidirectional I2C-bus
• Provides an SMBus voltage-level translator
• Low Side: 1.2 to 3.3 V
• High Side: 1.8 to 5.5 V

The SparkFun Voltage-Level Translator Breakout - PCA9306 is a dual bidirectional I2C-bus and SMBus voltage-level translator that is operational on the low side from 1.2 to 3.3 V and on the high side from 1.8 to 5.5 V.

Simply apply your low and high-side reference voltages to the VREF1 and VREF2 respectively, connect your I/O and drive the Enable pin high to open bidirectional voltage translation without the use of a direction pin.
