: Usually NC (No Connection) or specific anode/cathode pins. Pin 2 : Anode (Input LED). Pin 3 : Cathode (Input LED). Pin 5 : GND (Output side). Pin 6 : Vout (Output Signal). Pin 7 : NC or Enable. Pin 8 : Vcc (Supply Voltage). Common Applications
: Isolation in solar inverters and wind turbine controllers. Important Note on the "1458" Part Number 1458 optocoupler datasheet
The HCPL-1458 is typically housed in an or DIP-8 package. While specific internal diagrams vary by variant, a standard high-speed 8-pin optocoupler often follows this general layout: : Usually NC (No Connection) or specific anode/cathode pins
: Protecting low-voltage control systems from the high voltages used in AC or DC motor drives. 1458 optocoupler datasheet
