Maxim has introduced the MAX7356/MAX7357/MAX7358, 8-channel, I²C switches/multiplexers with bus lockup detection, isolation and notification. These 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. All devices are ideal for servers, base stations, data storage and other applications in which multiple I2C devices need to be addressed and controlled. Fully specified over the -40°C to +85°C extended temperature range, the multiplexers are available in 24-pin TSSOP and TQFN packages.
