Product Overview The MAX7321AEE+ is a I2C port expander with 8 open-drain I/O in 16 pin QSOP package. This 2-wire serial interfaced peripheral features an eight open-drain I/O ports with selectable internal pull-ups and transition detection. Any port may be used as a logic input or an open-drain output. Ports are overvoltage protected to +6V independent of supply voltage. All I/O ports configured as inputs are continuously monitored for state changes (transition detection). State changes are indicated by the open-drain INT(complementary) output. The interrupt is latched, allowing detection of transient changes. When MAX7321 is subsequently accessed through serial interface any pending interrupt is cleared. The open-drain outputs are rated to sink 20mA and are capable of driving LEDs. It is used in cell phones, SAN/NAS, servers, satellite radio and notebooks. Supply voltage range is 1.71V to 5.5V Operating temperature range from -40°C to 125°C 400KHz I2C serial interface 8 open-drain I/O ports rated to 20mA sink current Any port can be a logic input or an open-drain output Selectable I/O port power-up default logic states Transient changes are latched allowing detection between read operations INT(complementary) output alerts change on inputs Low 0.6µA (typ) standby current Low 0.6µA (typ) standby current Product Information Chip Configuration: - Bus Frequency: 400kHz IC Interface Type: I2C Supply Voltage Min: 1.71V Supply Voltage Max: 5.5V Interface Case Style: QSOP No. of Pins: 16Pins No. of I/O's: 8I/O's Product Range: - Automotive Qualification Standard: - MSL: MSL 1 - Unlimited
