MAX7325AEG+ is an I²C port expander. This 2-wire serial-interfaced peripheral features 16 I/O ports. Ports are divided into eight push-pull outputs and eight I/Os with selectable internal pullups and transition detection. Eight ports are push-pull outputs and eight I/Os may be used as a logic input or an open-drain output. Ports are overvoltage protected to +6V. All I/O ports configured as inputs are continuously monitored for state changes (transition detection). State changes are indicated by the INT output. The interrupt is latched, allowing the detection of transient changes. When the MAX7325 is subsequently accessed through the serial interface, any pending interrupt is cleared. The open-drain outputs are rated to sink 20mA, and are capable of driving LEDs. The RST input clears the serial interface, terminating any I²C communication to or from the MAX7325. It is used in applications such as cell phones, SAN/NAS, servers, notebooks, satellite radio, automotive.
