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 sig nal a logic high

state by transmit ting 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. The HCPL-4200 aids in the design process

by providing guaranteed thresholds for logic high state and

logic low state for the current loop, providing an LSTTL,

TTL, or CMOS compatible logic interface, and providing

guaranteed common mode rejection. The bu er circuit

on the current loop side of the HCPL-4200 provides typi-

cally 0.8 mA of hysteresis which increases the immunity to

common mode and di erential mode noise. The bu er also

provides a controlled amount of LED drive current which

takes into account any LED light output degradation. The

internal shield allows a guaranteed 1000 V/µs common

mode transient immunity.

Cross talk and common mode coupling are greatly reduced when optical isolation is implemented at the same end of both loops, as shown. The full duplex data rate is limited by the non-isolated active receiver current loop. Comments mentioned under simplex configuration apply to the full duplex case.
