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 I 2C bus to one or more channels at a time. These devices isolate bus loading by extending the I2C bus onto different channels. The.

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 I 2C 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 I 2 C 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 a 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.

These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
