Applications
Data transfer between equipment which employs cur-
rent loop circuits can be accomplished via one of three
configurations: simplex, half duplex or full duplex com-
munication. With these configurations, point-to-point
and multidrop arrange ments are possible. The appropri-
ate configuration to use depends upon data rate, num-
ber of stations, number and length of lines, direction of
data flow, protocol, current source location and voltage
compliance value, etc.
Simplex
The simplex configuration, whether point to point or
multi drop, gives unidirectional data flow from transmit-
ter to receiver(s). This is the simplest configuration for use
in long line length (two wire), for high data rate, and low
current source compliance level applications. Block dia-
grams of simplex point-to-point and multidrop arrange-
ments are given in Figures 17a and 17b respectively for
the HCPL-4200 receiver optocoupler.

Figure 15. Typical Logic Low Enable Propagation Delay vs. Temperature.
For the highest data rate per formance in a current loop,
the configuration of a non-isolated active transmitter
(containing current source) transmitting data to a re-
mote isolated receiver(s) should be used. When the cur-
rent source is located at the trans mitter end, the loop is
charged approximately to V
the current source is located at the receiver end, the loop
is charged to the full compliance voltage level. The lower
the charged voltage level the faster the data rate will be.
In the configurations of Figures 17a and 17b, data rate is
independent of the current source voltage compliance
level. An adequate compliance level of current source
must be available for voltage drops across station(s) dur-
ing the MARK state in multi drop applications or for long
line length. The maximum compliance level is deter-
mined by the trans mitter breakdown characteristic.
