DollaTek PCA9306 2-bit Bidirectional IIC Bus and SMBus Voltage-Level Translator Module

• The PCA9306 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 PCA9306 device can be used to isolate a 400-kHz bus from a 100-kHz busby controlling the EN pin, and disconnecting the slower bus during fast-mode communication.
• Less than 1.5 ns maximum propagation delay to accommodate Standard-mode and;
• Fast-mode I2C-bus devices and multiple masters
