Philips launches I?C bus buffers

Philips Semiconductors has announced a family of I?C devices that will help designers build bigger I?C systems for maintenance and control applications in CompactPCI (PICMG2.9) and AdvancedTCA (PICMG3.X) architectures.

The PCA951x family of hot swappable I?C bus buffers (consists of the PCA9510/11/12/13/14) can also be used in normal I?C bus or SMBus applications. The devices communicate between system boards allowing insertion and removal of the boards into an active I?C system without corrupting the data on the I?C bus.

First in a series of hot swappable I?C bus buffers with enhanced features, each member of the PCA951x family is similar in operation, containing specific features depending upon the application need. The products are offered in both 8-pin SO and TSSOP (MSOP) packages, and are available in quantities of 10,000.
