This dual bidirectional I2C and SMBus voltage-level translator, with an enable (EN) input, is operational from 1.0V to 5.5V VREF1 and 1.8V to 5.5V VREF2.
The RS0302 allows bidirectional voltage translations between 1.0V 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.
In I2C applications, the bus capacitance limit of 400 pF restricts the number of devices and bus length. Using the halves of a bus; thus, more I RS0302 enables the system designer to isolate two 2C devices or longer trace length can be accommodated.
The RS0302 also can be used to run two buses, one at 400kHz operating frequency and the other at 100kHz operating frequency. If the two buses are operating at different frequencies, the 100kHz bus must be isolated when the 400kHz operation of the other bus is required. If the master is running at 400kHz, the maximum system operating frequency may be less than 400kHz because of the delays added by the repeater.
The RS0302 are available in green SOT23-8 and DFN1.4x1.0-8L packages. It operates over an ambient temperature range of -40°C to +85°C.
