* Propagation Delay: Less than 5.5ns
* Acceptable Voltage Reference 1.2V VREF1 and 1.8V, 2.5V, 3.3V, or 5V VREF2 1.8V VREF1 and 2.5V, 3.3V, or 5V VREF2 2.5V VREF1 and 3.3V or 5V VREF2 3.3V VREF1 and 5V

Applications

* the connections of the devices and bus length are limited as the 400pF capacitance of the bus pin. However, SGM4551B allows the isolation between two sides of I2C bus so that more and more I2C devices can be added and connected with SGM4551B. Two different kinds of bus frequencies are supported by
