PCA9514 - Hot swappable I2C and SMBus bus buffer

Download the PCA9514 datasheet PDF. This datasheet also covers the PCA9513 variant, as both devices belong to the same hot swappable i2c and smbus bus buffer family and are provided as variant models within a single manufacturer datasheet.

General Description

The PCA9513 and PCA9514 are hot swappable I2C and SMBus buffers that allows I/O card insertion into a live backplane without corrupting the data and clock buses.

INTEGRATED CIRCUITS PCA9513; PCA9514 Hot swappable I2C and SMBus bus buffer Product data sheet Supersedes data of 2004 Jan 07 2004 Oct 05 Philips Semiconductors Philips Semiconductors Hot swappable I2C and SMBus bus buffer Product data sheet PCA9513; PCA9514 DESCRIPTION The PCA9513 and PCA9514 are hot swappable I2C and SMBus buffers 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 PCA9511, PCA9513, and PCA9514 provides bi-directional buffering, keeping the backplane and card capacitances isolated.
