PCA9306DCUT

The PCA9306DCUTE4 is a dual bidirectional I?C and SMBus Voltage-level Translator with an enable (EN) input, is operational from 1.2 to 3.3V VREF1 and 1.8 to 5.5V VREF2. The PCA9306DCUTE4 allows bidirectional voltage translations between 1.2 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. When EN is low, the translator switch is off and a high-impedance state exists between ports. In addition to voltage translation, the PCA9306 can be used to isolate a 400kHz bus from a 100kHz by controlling the EN pin.
