Supply Voltage Input (Requires a 0.1 µF bypass capacitor close to Pin 5) Primary Applications

The —frequently cataloged in manufacturer portfolios as the HCPL-1458 , HCPL-A1458 , or HCNW1458 —is a premier, hermetically sealed, high-speed digital logic gate optoisolator. Originally engineered by Avago Technologies (now Broadcom), this component targets demanding electronic layouts requiring absolute electrical isolation. It acts as a safety barrier and noise-reduction bridge between low-voltage digital control circuits (like microcontrollers) and high-voltage power networks.
