Shown in Figures 15 and 16 is the
driver interface circuit using a NPN
(2N3904) general-purpose
transistor. Since, in a V
CC
common
configuration (HCPL-0560) LED
anode for one channel is connected
to the V
CC
pin of the second
channel, LED input current now
becomes a direct function of the
power supply voltage. Thus, care
must be taken to use an
appropriate current limiting
resistor, the value of which will be
a function of the common supply
voltage.

Table A below lists the
recommended R
F
(series drive
current limiting resistor) and R
L
(output pull-up load resistor) for
the HCPL-0560 optoisolator. The
R
F
values chosen will limit the
input drive current at the minimum
recommended value of 16 mA. The
R
L
value chosen at each supply
voltage will guarantee an output
current does not exceed the
maximum current consistent with
the minimum specified CTR of
15%. Similarly, Table B lists the
recommended R
F
and R
L
for the
HCPL-0561 configuration.
Figure 17 shows an RS-232-E
isolated interface using the
HCPL-0560. The LED is shown
driven with a NPN transistor
(2N3904). The input series
current limiting resistor R
F
(200
) sets the LED current at
16 mA minimum required for the
optoisolator. The pull-up resistor
R
L
(1.9 k
) assures that the
optoisolator output will saturate
and conduct current consistent
with the minimum CTR of 15%.
The output of the optoisolator is
shown to interface directly with
DS14C232 (transceiver for
RS-232-E) driver input. The
output of the transceiver is shown
to drive the input of NPN
Transistor (2N3904). This NPN
transistor is configured to drive
the LED of the optoisolator.
Similarly Figure 18 shows an
RS-232-E isolated interface using
the HCPL-0561. Again, NPN
transistor 2N3904 is used to drive
the LED of the optoisolator. And
the output of the optoisolator is
directly connected to the driver
input of the transceiver
(DC14C232).
