A1458 Optocoupler Datasheet Jun 2026

The is a high-speed, reliable solution for isolating sensitive logic components from high-voltage, high-noise environments. Its 1 Mb/s speed,

Always place a small ceramic bypass capacitor ( a1458 optocoupler datasheet

If the output only drops to 1.5V, the A1458 has a damaged phototransistor or a false datasheet. The is a high-speed, reliable solution for isolating

Often used in motor drives to drive IGBTs or power MOSFETs, separating high-voltage power stages from low-voltage controllers. Commonly available in an 8-pin Dual In-line Package

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.

Commonly available in an 8-pin Dual In-line Package (DIP) or Surface Mount Device (SMD) outline.
