ISOCOM ISP847X 4-Channel Optocoupler, DIP-16, 5.3kV

The ISOCOM ISP847X is a high-performance, 4-channel optically coupled isolator designed for critical signal isolation applications. Housed in a compact 16-pin Dual In-line Package (DIP), it provides a robust solution for separating circuits of different potentials and impedances, safeguarding sensitive electronic components from voltage spikes and noise.

At its core, the device utilises infrared light emitting diodes (IREDs) coupled with NPN silicon phototransistors. This optical coupling method ensures excellent electrical isolation, with a high isolation voltage rating of 5.3kV, making it suitable for demanding industrial environments. It is an ideal choice for enhancing the reliability and safety of system controllers and data transmission lines.
