Maxim Integrated Products has released the MAX7356/MAX7357/MAX7358, 8-channel, I?C switches/muxes with bus lockup detection, isolation and notification.

The devices enable a master to isolate slaves that may otherwise have address conflicts and to communicate with each of them individually. The MAX7357 and MAX7358 employ an integrated timer to monitor all extended buses for lockup conditions. Additionally, these two parts can be set to send a "flush-out" sequence on the faulty channel to clear the bus lockup condition. The MAX7356/MAX7357/MAX7358 are ideal for servers, base stations, data storage and other applications in which multiple I?C devices need to be addressed and controlled.

Fully specified over the -40C to +85C extended temperature range, the MAX7356/MAX7357/MAX7358 are available in 24-pin TSSOP and TQFN packages. Prices start at $1.37 (1,000-up, FOB USA).
