PCA9510A Datasheet (NXP Semiconductors) - Hot swappable I2C-bus and SMBus bus buffer

PCA9510A, Hot swappable I2C-bus and SMBus bus buffer

The PCA9510A is a 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 command or bus idle occurs on the backplane without bus co
