Additional Details:

The LTV-846M typically consists of an LED on the input side and a phototransistor on the output side. When current flows through the LED, it emits light, which activates the phototransistor and allows current to flow through the output circuit. Key electrical specifications include the forward current of the input LED, the collector-emitter voltage and current of the output transistor, and the isolation voltage between input and output. Package type is generally DIP-16 or similar. Specific CTR values vary, consult the datasheet for precise specifications based on different current levels. The operating temperature range is typically -30°C to +100°C.
