PCA9306FMUTCG

The PCA9306FMUTCG is a dual bidirectional I²C-bus and SMBus Voltage-level Translator with an enable (EN) input. It allows bidirectional voltage translations between 1 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. The PCA9306FMUTCG is not a bus buffer that provides both level translation and physical capacitance isolation to either side of the bus when both sides are connected. The PCA9306FMUTCG only isolates both sides when the device is disabled and provides voltage level translation when active. It can be used to run two buses, one at 400kHz operating frequency and the other at 100kHz operating frequency.
