Additional Details

The S-80841 series voltage detectors typically feature an open-drain output, requiring an external pull-up resistor. The specific threshold voltage is determined by the part number (4.1V in this case, based on '41' in the name). The operating temperature range is usually between -40°C and +85°C. The ED5 likely indicates a specific release delay time.
