HCPL-4200 Optically Coupled 20 mA Current Loop Receiver Data Sheet Lead (Pb) Free RoHS 6 fully compliant RoHS 6 fully compliant options available; -xxxE denotes a lead-free product 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 to the logic output breaks ground loops and provides for a very high common mode rejection.
