MAX7368EUE+ Datasheet MAX7368EUE+, MAX7367EUP+, MAX7369EUP+ | P1-P3

General Description

The MAX7367/MAX7368/MAX7369 bidirectional, four-

channel I

C switches/multiplexer expand the main I

bus up to four extended buses. The MAX7369 1:4

multiplexer connects the main I

C bus to one channel

at a time. The MAX7367/MAX7368 four-channel

switches connect the main I

C bus to one or more

channels at a time.

These devices isolate bus loading by extending the I

bus onto different channels. The MAX7367/MAX7368/

MAX7369 allow more devices to be interconnected to a

master controller and multiple devices with the same

C address to communicate to a master. The channels

are selected through the main I

C bus by writing to the

internal control register of the device.

Any device connected to an I

C bus can transmit and

receive signals. The MAX7367/MAX7368/MAX7369 are

transparent to signals sent and received at each chan-

nel, allowing multiple masters. These devices are com-

patible with the I

C protocol of clock stretch,

synchronization, and arbitration in case multiple mas-

ters 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 pow-

ered up. The MAX7367/MAX7369 have interrupt inputs,

allowing devices on the extended bus to send an inter-

rupt 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.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. 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.
