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

Product OverviewThe MAX7322AEE+ is an I2C port expander with 4 push-pull outputs and 4 inputswith selectable internal pull-ups in 16 pin QSOP package. Input ports areovervoltage protected to +6V and have transition detection with interruptoutput. The four input ports are continuously monitored for state changes(transition detection). The interrupt is latched allowing detection of transientchanges. Any combination of inputs can be selected using the interrupt mask toassert open-drain active-low INT output. The four push-pull outputs are rated tosink 20mA and are capable of driving LEDs. The active-low RST input clears theserial interface by terminating any I2C communication to or from MAX7322.Supply voltage range is 1.71V to 5.5VAutomotive temperature range from -40°C to 125°C400KHz I2C serial interface4 input ports with maskable, latching transition detectionTransient changes are latched by allowing detection between read operationsActive-low INT output alerts change on any selection of inputsLow standby current of 0.6µASupply current (interface running) of 23µA (fSCL = 400KHz, other digital inputsat V+)Product InformationChip Configuration: -Bus Frequency: 400kHzIC Interface Type: I2CSupply Voltage Min: 1.71VSupply Voltage Max: 5.5VInterface Case Style: QSOPNo. of Pins: 16PinsNo. of I/O's: 4I/O'sProduct Range: -Automotive Qualification Standard: -MSL: MSL 1 - Unlimited
