Overview

INTEGRATED CIRCUITS PCA9511 Hot swappable I2C-bus and SMBus bus buffer Product data sheet Replaces data sheet PCA9510; PCA9511 of 2006 Aug 15 2006 Aug 23 Philips Semiconductors Philips Semiconductors Hot swappable I2C-bus and SMBus bus buffer Product data sheet PCA9511 DESCRIPTION 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 command 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 and card capacitances isolated.
The PCA9511 rise time accelerator circuitry allows the use of weaker DC pull-up currents while still meeting rise time requirements to prevent interference when there are multiple devices in the same system.
The PCA9511 incorporates a digital ENABLE input p...
