Description
These bi-directional dual channel
optoisolators, packaged in an
industry standard SOIC-8
package, provide full duplex and
bi-directional isolated data
transfer and communication
capability in a compact surface
mount package.
These optoisolators contain two
pairs of emitters and detectors
packaged in a unique configur-
ation to allow simultaneous,
isolated, bi-directional transmit
and receive capability in a single
package. Separate photo-detector
and output stage allows a speed
performance hundreds of times
faster than a conventional photo-
transistor coupler by minimizing
the base-collector capacitance
and charge storage effects.
The HCPL-0560 is a VCC common
configuration, in which anode of
the LED of one channel is
internally connected to the output
side VCC of the second channel.
Thus, the LED input current of
one channel now becomes a
function of the VCC of the second
channel in the package, and
appropriate care is required so as
not to overdrive the LEDs.

Application Information
The HCPL-0560 (common VCC
configuration) and HCPL-0561
(common GND configuration)
optoisolators are ideal for use in
bi-directional data transmission
and communication applications.
Each of the two configurations
contains two optoisolators each
in an industry standard SOIC-8
package. Bi-directional here
implies that there are two
emitter-detector pairs assembled
in opposite direction across the
isolation barrier. This allows
simultaneous, bi-directional, full
duplex data transmission
capability within a single
optoisolator package.
The HCPL-0560 is internally
connected in a “common VCC”
configuration, which means that
the LED anode of one channel is
connected to the VCC pin of the
second channel on each side of
the isolation barrier. The HCPL-
0561 is internally connected in a
“common GND” configuration,
which means that the LED
cathode of one channel is
connected to the emitter or GND
of the second channel on each
side of the isolation barrier.
Having a maximum guaranteed
speed of 1 Mbd the HCPL-0560
and HCPL-0561 are ideal for
applications involving the
RS-232-E (TIA/EIA-232) data
transmission standard. If these
optoisolators are used in
RS-232-E applications, it is
understood that the optoisolators
will be used in conjunction with
an appropriate transceiver of the
RS-232-E standard.
The common VCC configuration
(HCPL-0560) transmits non-
inverting signal with respect to
the cathode voltage of the LED
pins (4,8) in the driver
configuration shown Figure 15.
When the input signal at the base
of the driver transistor (2N3904)
is high, the input LED conducts
drive current, and allows the
output of the optoisolator to be in
the low state. Thus, when the
cathode voltage is low (LED ON)
the output is low, and when the
cathode voltage is high (LED
OFF) the output will be high. In
other words, HCPL-0560 can be
considered to transmit non-
inverting signal. The common
GND configuration (HCPL-0561)
transmits inverting signal with
respect to the anode voltage of
the LED pins (4,8) in the driver
configuration shown in Figure 16.
