PCA9512 Level Shifting Hot Swappable I2C And SMBus Buffer

The PCA9512 is a hot swappable I2C and SMBus Buffer that 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 V and 5 V systems while maintaining the best noise margin for each voltage level. Either pin may be powered with supply voltages ranging from 2.7 V to 5.5 V 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 PCA9512 provides bi-directional buffering, keeping the Backplane and card capacitances isolated. The dynamic offset design of the PCA9510 11/12/13/14 I/O drivers allow them to be connected to another PCA9510 11/12/13/14 device in series or in parallel and to the A side of the PCA9517. The PCA9510 11/12/13/14 CAN not connect to the static offset I/Os used on the PCA9515 15A/16/16A/17 B side and PCA9518.
