Switch Detection Interface, 22-switches, 3.3 V / 5.0 V SPI , SOICW-EP 32

The 恩XP? MC33978 is a multiple switch detection interface (MSDI) designed to detect the closing and opening of up to 22 switch contacts. The switch status, either open or closed, is transferred to the microprocessor through a SPI in automotive environments.\nThis SMARTMOS? device features a 24-to-1 ? Designed to operate 4.5 V ≤ VBATP ≤ 36 V\n? Switch input voltage range -14 V to VPWR, 36 V Max.\n? Interfaces directly to an MCU using 3.3 V / 5.0 V SPI protocol ? Selectable wake-up on change of state\n ? Selectable wetting current (2, 6, 8, 10, 12, 14, 16, or 20 mA)\n? 8 programmable inputs (swi;
