The MAX7321AEE+ is an 8-bit serial-interfaced peripheral from Analog Devices / Maxim Integrated, designed for IO expansion. It features eight open-drain I/O ports that can function as logic inputs or outputs. These ports are overvoltage protected to +6V and rated to sink 20mA, making them suitable for driving LEDs.
The device utilizes a 400kHz I2C serial interface for communication and supports 16 slave addresses via two address input pins (AD0 and AD2). All I/O ports configured as inputs are continuously monitored for state changes, with an open-drain INT output signaling transitions. This interrupt is latched, allowing detection of transient changes between read operations.
The MAX7321AEE+ operates over a voltage range of +1.71V to +5.5V and is specified for an automotive temperature range of -40°C to +125°C. It is available in a 16-pin QSOP package, suitable for surface mounting.
This port expander is part of a family offering various input, open-drain, and push-pull output configurations, making it a versatile component for applications in cell phones, SAN/NAS, servers, notebooks, and satellite radio.
