MAX7358EUG+ (MAXIM INTEGRATED PRODUCTS)

The MAX7358EUG+ is a 8-channel I?C switches/multiplexers with bus lock-up detection, isolation and notification in 24 pin TSSOP package. It feature an enhanced mode with built-in timer used to monitor all extended buses for lock-up conditions. If the clock or data line of any of these buses is low for more than 25ms (typ), a lock condition is detected. There is an optional pre-connection check that can be enabled to toggle the extended bus clock and data line low then high to ensure the downstream bus is not locked high prior to connecting it to the host bus. The device expands I2C bus to any combination of 8 extended I2C buses. It enables a master on the main bus to isolate and communicate with devices or groups of devices that may otherwise have slave address conflicts. MAX7358 is transparent to signals sent and received at each channel which allows multiple masters.
