PCA9510—支持热插拔的I2C SMBus缓冲器产品数据手册

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 contenTIon on the card. When the

connection is made, the PCA9510A provides bidirectional buffering, keeping the

backplane and card capacitances isolated.
