HCPL-3700 AC/DC to Logic Interface Optocoupler Absolute Maximum Ratings (No derating required up to 70°C) Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be operable above the recommended operating conditions and stressing the parts to these levels is not recommended. In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability.
