General Description

The HCPL-4200 optocoupler is designed to operate as a receiver in equipment using the 20 mA Current Loop.

20 mA current loop systems conventionally signal a logic high state by transmitting 20 mA of loop current (MARK), and signal a logic low state by allowing no more than a few milliamperes of loop current (SPACE).

Optical coupling of the signal from the 20 mA current loop
