Each unit contains a light emit-
ting diode (LED), a threshold
sensing input buffer IC, and a
high gain photon detector to
provide an optocoupler which
permits adjustable external
threshold levels. The input buffer
circuit has a nominal turn on
threshold of 2.5 mA (I
TH+
) and
3.6 volts (V
TH+
). The addition of
one or more external attenuation
resistors permits the use of this
device over a wide range of input
voltages and currents. Threshold
sensing prior to the LED and
detector elements minimizes
effects of any variation in optical
coupling. Hysteresis is also
provided in the buffer for extra
noise immunity and switching
stability.
The buffer circuit is designed
with internal clamping diodes to
protect the circuitry and LED
from a wide range of over-voltage
and over-current transients while
the diode bridge enables easy use
with ac voltage input.
These units combine several
unique functions in a single
package, providing the user with
an ideal component for computer
input boards and other applica-
tions where a predetermined
input threshold optocoupler level
is desirable.
The high gain output stage
features an open collector output
providing both TTL compatible
saturation voltages and CMOS
compatible breakdown voltages.
This is an eight pin DIP which
may be purchased with a variety
of lead bend and plating options.
See Selection Guide Table for
details. Standard Microcircuit

2. Measured at a point 1.6 mm below

, must be

The typical thermal resistance from
junction to case is equal to 170

9. Device considered a two terminal
device: Pins 1, 2, 3, 4 connected
together, Pins 5, 6, 7 8 connected
together.
10. This is a momentary withstand test,
not an operating condition.
11. The t
PHL
propagation delay is
measured from the 2.5 V level of the
leading edge of a 5.0 V input pulse (1
s rise time) to the 1.5 V level on the
leading edge of the output pulse (see
Figure 7).
12. The t
PLH
propagation delay is
measured from the 2.5 V level of the
trailing edge of a 5.0 V input pulse (1
s fall time) to the 1.5 V level on the
trailing edge of the output pulse (see
Figure 7).
13. Common mode transient immunity in
Logic High level is the maximum
tolerable dV
CM/dt
of the common mode
voltage, V
CM
, to ensure that the output
will remain in a Logic High state (i.e.,
V
O
> 2.0 V). Common mode transient
immunity in Logic Low level is the
maximum tolerable dV
CM/dt
of the
common mode voltage, V
CM
, to ensure
that the output will remain in a Logic
Low state (i.e., V
O
< 0.8 V). See
Figure 8.
14. In applications where dV
CM/dt
may
exceed 50,000 V/
s (such as static
discharge), a series resistor, R
CC
,
should be included to protect the
detector IC from destructively high
surge currents. The recommended
value for R
CC
is 240
per volt of
allowable drop in V
CC
(between Pin 8
and V
CC
) with a minimum value of
240

Electrical Considerations
The HCPL-5760, HCPL-5761,
HCPL-576K or 5962-89477
optocoupler has internal
temperature compensated,
predictable voltage and current
threshold points which allow
selection of an external resistor,
R
x
, to determine larger external
threshold voltage levels. For a
desired external threshold
voltage, V
, a corresponding
typical value of R
x
can be
obtained from Figure 10. Specific
calculation of R
x
can be obtained
from Equation (1) of Figure 11.
Specification of both V
+
and V
-
voltage threshold levels simulta-
neously can be obtained by the
use of R
x
and R
p
as shown in
Figure 11 and determined by
Equations (2) and (3).
R
x
can provide over-current
transient protection by limiting
input current during a transient
condition. For monitoring
contacts with a relay or switch,
the HCPL-5760/1/K, or
5962-89477 combination with R
x
and R
p
can be used to allow a
specific current to be conducted
through the contacts for cleaning
purposes (wetting current).
The choice of which input voltage
clamp level to choose depends
upon the application of this
device (see Figure 3). It is
recommended that the low clamp
condition be used when possible
to lower the input power
dissipation as well as the LED
current, which minimizes LED
degradation over time.
In applications where dV
CM/dt
may
be extremely large (such as static
discharge), a series resistor, R
CC
,
should be connected in series
with V
CC
and Pin 8 to protect the
Figure 10. Typical External Threshold
Characteristic, V
vs. R
x
.
detector IC from destructively
high surge currents. See note 14
for determination of R
CC
. In
addition, it is recommended that a
ceramic disc bypass capacitor of
0.01
F to 0.1 F be placed
between Pins 8 and 5 to reduce
the effect of power supply noise.
For interfacing ac signals to TTL
systems, output low pass filtering
can be performed with a pullup
resistor of 1.5 k
and 20 F
capacitor. This application
requires a Schmitt trigger gate to
avoid slow rise time chatter
problems. For ac input applica-
tions, a filter capacitor can be
placed across the dc input
terminals for either signal or
transient filtering.
Either ac (Pins 1, 4) or dc (Pins
2, 3) input can be used to
determine external threshold
levels.
For one specifically selected
external threshold voltage level
V

-

can be determined

For two specifically selected
external threshold voltage levels,

will permit this selection via
