MAX7357EUG+

The MAX7357EUG+ is a 1 to 8 I2C bus switch/multiplexer with bus lock-up detection, isolation and notification 24 pin TSSOP package. This 8-channel device expands the main I2C bus to any combination of 8 extended I2C buses. The MAX7357 feature an enhanced mode that includes a built-in timer used to monitor all extended buses for lock-up conditions If clock or data line of any of these buses is low for more than 25ms, a lock condition is detected. An optional interrupt can be generated through bidirectional active-low RST/active-low INT. It is used in servers, RAID, base stations, control and automation devices, SFP control interface, networking equipment.

• Supply voltage range is 2.3V to 3.6V (3.3 supply), 4.5V to 5.5V (5V supply)
• Operating temperature range from -40°C to 85°C, bus lock-up detection and isolation
• Enhanced mode, preconnection wiggle test (enhanced mode only), enhanced mode power-up test
• Dual function active-low RST/active-low INT provides lock-up notification and hardware reset
• Supply current of 90µA (enhanced mode), standby current is 0.2µA (5V supply)
• Host notification on detection of lock-up, maintain fault diagnostic information
• 3 address control inputs, low RON switches, logic level translation
• Low 0.1µA (typ) standby current, supports hot insertion
• 100Kbps standard mode or 400Kbps fast mode I²C interface
• Address translation allows multiple device with same ID, 5.5V tolerant inputs
