Additional Details

The LTV-702V-AD optocoupler typically operates with a forward current (IF) of around 20mA and a collector-emitter voltage (VCEO) that varies depending on the specific application requirements. The isolation voltage is a key parameter, often rated in the kilovolts range. Detailed specifications are available in the Lite-On Inc. datasheet for this product.
