: For high-speed data communication across different ground planes. Motor Control 1458 optocoupler datasheet
The "1458" optocoupler (assumed common through-hole transistor-output optocoupler family; e.g., generic PC817-like single-channel phototransistor optocoupler) provides electrical isolation between input (LED) and output (phototransistor). Typical use cases: microcontroller isolation, signal level shifting, noise suppression, and protecting low-voltage logic from high-voltage circuits. | If you need
