UNISONIC TECHNOLOGIES CO., LTD UCA9306 DUAL BIDIRECTIONAL I2C BUS AND SMBUS VOLTAGE-LEVEL TRANSLATOR CMOS IC  DESCRIPTION The UTC UCA9306 device is a dual bidirectional I2C and SMBus voltage-level translator with an enable(EN) input, and is operational from 1.2-V to 3.3-V VREF1 and 1.8-V to 5.5-V VREF2. The UTC UCA9306 device allows bidirectional voltage translations between 1.2V and 5V,without the use of a direction pin .The low ON-state resistance (RON) of the switch allows connections to be made with minimal propagation delay. When EN is high, the translator switch is ON , and the SCL1 and SDA1 I/O are connected to the SCL2 and SDA2 I/O, respectively, allowing bidirectional data flow between ports.
