CD1020 interface equivalent, 22-channel multiple switch detection interface.
Features and benefits
* Fully functional operation from 6.0 V to 36 V
* Full parametric operation from 6.0 V to 28 V
* Low-power mode current IBATP = 30 μA an.
The CD1020 is a cost-optimized switch detection interface device (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 unit (MCU) through a Serial.
