PCA9511 Overview
The PCA9511 is a are hot swappable I2C-bus and SMBus buffer that allows I/O card insertion into a live backplane without corrupting the data and clock buses. Control circuitry prevents the backplane from being connected to the card until a STOP mand or bus idle occurs on the backplane without bus contention on the card. When the connection is made, the PCA9511 provides bidirectional buffering, keeping the backplane...
