Switch Detection Interface, 22-switches with Suppressed Wakeup, 3.3 V / 5.0 V SPI , SOIC 32

The 恩XP? MC33972 multiple switch detection interface with suppressed wake-up is designed to detect the closing and opening of up to 22 switch contacts.\nThe switch status, either open or closed, is transferred to the MCU through a SPI \nFeatures a 22-to-1 analog multiplexer for reading inputs as ana ? Interfaces directly to microprocessor using 3.3 V / 5.0 V SPI protocol\n? Selectable wake-up on change of state\n? Eight programmable inputs (switches to battery or ground)\n? Fourteen switch-to-ground inputs\n? Active Interrupt (INT) on change-of-switch state\n? Switch Voltage Range -14 – VPWR\n?;
