电平移位热插拔的I2C总线和SMBus总线缓冲器 Level shifting hot swappable I2C-bus and SMBus bus buffer

The is a level shifting hot swappable I²C-bus and SMBus bus Buffer allows I/O card insertion into a live backplane without corruption of the data and clock buses and includes two dedicated supply voltage pins to provide level shifting between 3.3 and 5V systems while maintaining the best noise margin for each voltage level. Either pin may be powered with supply voltages ranging from 2.7 to 5.5V with no constraints on which supply voltage is higher. Control circuitry prevents the backplane from being connected to the card until a stop-bit or bus idle occurs on the backplane without bus contention on the card. When the connection is made, the buffer provides bi-directional buffering, keeping the backplane and card capacitances isolated.
