The PCA9306DC1 is a dual bidirectional I2C-bus and SMBus voltage-level translator with an enable (EN) input, and is operational from 1.0 V to 3.6 V (Vref(1)) and 1.8 V to 5.5 V .
The PCA9306 is not a bus buffer like the PCA9509 or PCA9517A that provide both level translation and physically isolate the capacitance to either side of the bus when both sides are connected. The PCA9306 only isolates both sides when the device is disabled and provides voltage level translation when active.
The PCA9306 can also be used to run two buses, one at 400 kHz operating frequency and the other at 100 kHz operating frequency. If the two buses are operating at different frequencies, the 100 kHz bus must be isolated when the 400 kHz operation of the other bus is required. If the controller is running at 400 kHz, the maximum system operating frequency may be less than 400 kHz because of the delays added by the translator.
