Maxim Integrated (MAX7322AEE+) I/O Expander, 400 kHz

Product Overview The MAX7322AEE+ is an I2C port expander with 4 push-pull outputs and 4 inputs with selectable internal pull-ups in 16 pin QSOP package. Input ports are overvoltage protected to +6V and have transition detection with interrupt output. The four input ports are continuously monitored for state changes (transition detection). The interrupt is latched allowing detection of transient changes. Any combination of inputs can be selected using the interrupt mask to assert open-drain active-low INT output. The four push-pull outputs are rated to sink 20mA and are capable of driving LEDs. The active-low RST input clears the serial interface by terminating any I2C communication to or from MAX7322. Supply voltage range is 1.71V to 5.5V Automotive temperature range from -40°C to 125°C 400KHz I2C serial interface 4 input ports with maskable, latching transition detection Transient changes are latched by allowing detection between read operations Active-low INT output alerts change on any selection of inputs Low standby current of 0.6µA Supply current (interface running) of 23µA (fSCL = 400KHz, other digital inputs at V+) 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: 4I/O's Product Range: - Automotive Qualification Standard: - MSL: MSL 1 - Unlimited
