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.
