NCA9306 Dual Bidirectional I2C Bus and SMBus Voltage-Level Translator Datasheet (EN) 1.2 Product Overview The NCA9306 device is a dual bidirectional I2C and SMBus voltage-level translator with an enable (EN) input, and is operational from 1.2V to 3.3V VREF1 and 1.8V to 5.5V VREF2. The NCA9306 device allows bidirectional voltage translations between 1.2 V and 5 V, 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 NCA9306 device can be used to isolate a 400kHz bus from a 100kHz bus by controlling the EN pin to disconnect the slower bus during fast-mode communication.
