WebJul 17, 2024 · The FODM611 optocoupler IC from ON Semiconductor is a single-channel optocoupler rated for up to 10 Mbps data rate (NRZ, 100 ns propagation delay). This device outputs at 5 V while offering high common mode transient noise immunity, making it ideal in industrial networks (CAN, RS485, and DeviceNet systems) or low-speed automotive … WebAug 27, 2024 · A: In simple terms, CTR indicates the efficiency of the optocoupler. If CTR is low, the input side will need more current drive to the LED in order to create sufficient current at the phototransistor for the output load. Higher CTR also provides some input/output margin as the LED ages.
