RS7LS9306 Dual Bidirectional I2C-bus And SMBus Voltage-Level Translator
■The RS7LS9306 is a dual bidirectional I²C-bus and SMBus voltage-level translator with an enable (EN) input, and is operational from 1.0 V to 3.3 V (VREF1) and 1.8 V to 5.5 V(VREF2).
■The RS7LS9306 allows bidirectional voltage translations between 1.0 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.
■The RS7LS9306 is not a bus buffer that provides both level translation and physically isolates to either side of the bus when both sides are connected. The RS7LS9306 only isolates both sides when the device is disabled and provides voltage level translation when active.
■The translator provides excellent ESD protection to lower voltage devices, and at the same time protects less ESD-resistant devices.
