are manufactured and tested on
a MIL-PRF-38534 certified line
and are included in the DESC
Qualified Manufacturers List,
QML-38534 for Hybrid
Microcircuits.
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 (ITH+) and
3.6 volts (VTH+). 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.

Notes:
1. Maximum operating frequency is
defined when output waveform (Pin 6)
attains only 90% of VCC with RL = 1.8
kΩ, CL = 15 pF using a 5 V square
wave input signal.
2. Measured at a point 1.6 mm below
seating plane.
3. Current into/out of any single lead.
4. Surge input current duration is 3 ms at
120 Hz pulse repetition rate. Transient
input current duration is 10 µs at
120 Hz pulse repetition rate. Note that
maximum input power, PIN, must be
observed.
5. Derate linearly above 100°C free-air
temperature at a rate of 4.26 mW/°C.
Maximum input power dissipation of
195 mW allows an input IC junction
temperature of 150°C at an ambient
temperature of TA = 125°C with a
typical thermal resistance from
junction to ambient of θJAi = 235°C/W.
The typical thermal resistance from
junction to case is equal to 170°C/W.
Excessive PIN and TJ may result in
device degradation.
6. The 1.8 kΩ load represents 1 TTL unit
load of 1.6 mA and the 4.7 kΩ pull-up
resistor.
7. Logic low output level at Pin 6 occurs
under the conditions of VIN ≥ VTH+ as
well as the range of VIN > VTH – once
VIN has exceeded VTH+. Logic high
output level at Pin 6 occurs under the
conditions of VIN ≤ VTH- as well as the
range of VIN < VTH+ once VIN has
decreased below VTH-.
8. The ac voltage is instantaneous
voltage.
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 tPHL propagation delay is
measured from the 2.5 V level of the
leading edge of a 5.0 V input pulse (1
µs rise time) to the 1.5 V level on the
leading edge of the output pulse (see
Figure 7).
12. The tPLH propagation delay is
measured from the 2.5 V level of the
trailing edge of a 5.0 V input pulse (1
µs 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 dVCM/dt of the common mode
voltage, VCM, to ensure that the output
will remain in a Logic High state (i.e.,
VO > 2.0 V). Common mode transient
immunity in Logic Low level is the
maximum tolerable dVCM/dt of the
common mode voltage, VCM, to ensure
that the output will remain in a Logic
Low state (i.e., VO < 0.8 V). See
Figure 8.
14. In applications where dVCM/dt may
exceed 50,000 V/µs (such as static
discharge), a series resistor, RCC,
should be included to protect the
detector IC from destructively high
surge currents. The recommended
value for RCC is 240 Ω per volt of
allowable drop in VCC (between Pin 8
and VCC) with a minimum value of
240 Ω.
15. D1 and D2 are Schottky diodes; D3
and D4 are zener diodes.
16. Standard parts receive 100% testing at
25°C (Subgroups 1 and 9). SMD and
Class H parts receive 100% testing at
25, 125, and -55°C (Subgroups 1 and
9, 2 and 10 ,3 and 11, respectively.)
17. Parameters shall be tested as part of
device initial characterization and after
process changes. Parameters shall be
guaranteed to the limits specified for
all lots not specifically tested.

OPTOCOUPLERS
Electrical Considerations
The HCPL-5760, HCPL-5761, or
5962-89477 optocoupler has
internal temperature compen-
sated, predictable voltage and
current threshold points which
allow selection of an external
resistor, Rx, to determine larger
external threshold voltage levels.
For a desired external threshold
voltage, V±, a corresponding
typical value of Rx can be
obtained from Figure 10. Specific
calculation of Rx 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 Rx and Rp as shown in
Figure 11 and determined by
Equations (2) and (3).
Rx 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, or 5962-89477
combination with Rx and Rp 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 dVCM/dt may
be extremely large (such as static
discharge), a series resistor, RCC,
should be connected in series
with VCC and Pin 8 to protect the
detector IC from destructively

Characteristic, V± vs. Rx.
high surge currents. See note 14
for determination of RCC. In
addition, it is recommended that a
ceramic disc bypass capacitor of
0.01 µF to 0.1 µF 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 kΩ and 20 µF
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+ or V-, Rx can be determined
without use of Rp via
V+ - VTH+

Rx = ––––––––– (1)
ITH+
(-) See Application Note 1004 for
more information.
For two specifically selected
external threshold voltage levels,
V+ and V-, the use of Rx and Rp

equations (2), (3) provided the
following conditions are met:
RP =
VTH- (V+) - VTH+ (V-)
