Pin Functional Descriptions Pin No. 1 2 3 4 Name VIN GND OUT/OUT VCC Description Monitors analog input voltage Ground Digital output. Active-high or active-low and open-drain or push-pull options depending on model number Power supply ESD CAUTION ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the human body and test equipment and can discharge without detection. Although this product features proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality. ` Rev.
