without adversely affecting the
parametric performance.
These dual channel optocouplers
are available in an 8-Pin DIP and
in an industry standard SO-8
package. The following is a cross
reference table listing the 8-Pin
DIP part number and the
electrically equivalent SOIC-8 part
number.

The SO-8 does not require
“through holes” in a PCB. This
package occupies approximately
one-third the footprint area of the
standard dual-in-line package.
The lead profile is designed to be
compatible with standard surface
mount processes.
Guaranteed operation at low input
currents and the high current
transfer ratio (CTR) reduce the
magnitude and effects of CTR
degradation.
The outstanding high temperature
performance of this split
Darlington type output amplifier
results from the inclusion of an
integrated emitter-base bypass
resistor which shunts photodiode
and first stage leakage currents to
ground.
The HCPL-2731/0731 have a
400% minimum CTR at an input
current of only 0.5 mA making it
ideal for use in low input current
applications such as MOS, CMOS,
and low power logic interfacing or
RS232C data transmission
systems. In addition, the high
CTR and high output current
capability make this device
extremely useful in applications
where a high fanout is required.
Compatibility with high voltage
CMOS logic systems is guaranteed
by the 18 V V
CC
and V
O
specifica-
tions and by testing output high
leakage (I
OH
) at 18 V.
The HCPL-2730/0730 are speci-
fied at an input current of 1.6 mA
and have a 7 V V
CC
and V
O
rating.
The 300% minimum CTR allows
TTL to TTL interfacing at this
input current.
Important specifications such as
CTR, leakage current, and output
saturation voltage are guaranteed
over the 0°C to 70°C temperature
range to allow trouble-free system
operation. Selection for lower
input currents down to 250
µA
is
available upon request.
