Optocoupler Datasheet ^new^ — A1458

If you are designing a circuit or replacing a component:

The component often referred to as the in the context of optocouplers is the , a high-speed, hermetically sealed device manufactured by (formerly Avago/Agilent). Key Technical Specifications

Delivers the isolated output signal.

Digital logic transitions power an internal infrared LED. This emitted light crosses a physically isolated air gap or glass barrier inside the chip, completely preventing raw current from crossing between the input and output networks.

Features a maximum propagation delay (

The is a specialized high-speed optical isolation device engineered to provide robust galvanic isolation between low-voltage control signals and high-voltage power stages. It features an integrated driver designed to safely interface with power transistors such as IGBTs and power MOSFETs in demanding electrical environments.
