Description

The MAX7367/MAX7368/MAX7369 bidirectional, four-channel I²C switches/multiplexer expand the main I²C bus up to four extended buses. The MAX7369 1:4 multiplexer connects the main I²C bus to one channel at a time. The MAX7367/MAX7368 four-channel switches connect the main I²C bus to one or more channels at a time. These devices isolate bus loading by extending the I²C bus onto different channels. The MAX7367/MAX7368/MAX7369 allow more devices to be interconnected to a master controller and multiple devices with the same I²C address to communicate to a master. The channels are selected through the main I²C bus by writing to the internal control register of the device. Any device connected to an I²C bus can transmit and receive signals. The MAX7367/MAX7368/MAX7369 are transparent to signals sent and received at each channel, allowing multiple masters. These devices are compatible with the I²C protocol of clock stretch, synchronization, and arbitration in case multiple masters address the bus at the same time. All devices are set to the default state during initial power-up. The MAX7367/MAX7368 have an active-low RESET input allowing external circuitry to set the MAX7367/MAX7368 to its default state anytime after the device has powered up. The MAX7367/MAX7369 have interrupt inputs, allowing devices on the extended bus to send an interrupt signal to the master on the main bus. The MAX7367/MAX7369 are available in 20-pin TSSOP packages, and the MAX7368 is available in a 16-pin TSSOP package. All devices operate over the -40°C to +85°C extended temperature range.
