Description
Features
The HCPL-0370/3700 and HCPL-3760 are voltage/cur- • Standard (HCPL-0370/3700) and low input current
rent threshold detectionoptocouplers. The HCPL-3760 is
a low-current version of the HCPL-0370/3700. To obtain
lower current operation, the HCPL-3760 uses a high-effi-
ciency AlGaAs LED which provides higher light output at
(HCPL-3760) versions
• AC or DC input
• Programmable sense voltage
lower drive currents. The devices utilize threshold sens- • Hysteresis
ing input buffer ICs which permit control of threshold
levels over a wide range of input voltages with a single
external resistor.
• Logic compatible output
• Thresholds guaranteed over temperature
• Thresholds independent of LED optical parameters
The input buffer incorporates several features: hysteresis
for extra noise immunity and switching immunity, a di-
ode bridge for easy use with ac input signals, and inter-
nal clamping diodes to protect the buffer and LED from
a wide range of over-voltage and over-current transients.
Because threshold sensing is done prior to driving the
LED, variations in optical coupling from the LED to the
detector will have no effect on the threshold levels.
• Recognized under UL 1577 and CSA approved for
dielectric withstand proof test voltage of 3750 Vac, 1
minute
Applications
• Limit switch sensing
• Low voltage detector
• AC mains and DC link voltage detection
• Relay contact monitor
• Relay coil voltage monitor
• Current sensing

CAUTION: It is advised that normal static precautions be taken in handling and assembly
of this component to prevent damage and/or degradation which may be induced by ESD.
The HCPL-0370/3700’s input buffer IC has a nominal turn on threshold of 2.5 mA (ITH +) and 3.7 volts (VTH +).
The buffer IC for the HCPL-3760 was redesigned to permit a lower input current. The nominal turn on threshold for the
HCPL-3760 is 1.2 mA (ITH +) and 3.7 volts (VTH +).
The high gain output stage features an open collector output providing both TTL compatible saturation voltages and
CMOS compatible breakdown voltages.
By combining several unique functions in a single package, the user is provided with an ideal component for indus-
trial control computer input boards and other applications where a predetermined input threshold level is desirable.
Ordering Information
HCPL-0370/HCPL-3700/HCPL-3760 is UL Recognized with 3750 Vrms for 1 minute per UL1577 unless otherwise

1. Insulation characteristics are guaranteed only within the safety maximum ratings, which must be ensured by protective circuits within the
application.
2. Safety-limiting parameters are dependent on case temperature. The Input Current, IS,INPUT, derates linearly above 25°C free-air case temperature
at a rate of 1.2 mA/°C and 1.53 mA/°C for HCPL-0370 and HCPL-3700/3760 respectively; the Output Power, PS,OUTPUT, derates linearly above 25°C
free-air case temperature at a rate of 4.8 mW/°C and 4 mW/°C for HCPL-0370 and HCPL-3700/3760 respectively.

*The Input-Output Momentary Withstand Voltage is a dielectric voltage rating that should not be interpreted as an input-output continuous volt-
age rating. For the continuous voltage rating refer to the IEC/EN/DIN EN 60747-5-5 Insulation Characteristics Table (if applicable), your equipment
level safety specification, or Avago Application Note 1074, “Optocoupler Input-Output Endurance Voltage.”

Notes:
1. Measured at a point 1.6 mm below seating plane.
2. Current into/out of any single lead.
3. 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.
4. Derate linearly above 70°C free-air temperature at a rate of 4.1 mW/°C (HCPL-3700/3760) and 3.1 mW/°C (HCPL-0370). Maximum input power
dissipation of 230 mW (HCPL-3700/3760) and 172 mW (HCPL-0370) allows an input IC junction temperature of 125°C at an ambient tempera-
ture of TA = 70°C. Excessive PIN and TJ may result in IC chip degradation.
5. Derate linearly above 70°C free-air temperature at a rate of 5.4 mW/°C (HCPL-3700/3760) and 5 mW/°C (HCPL-0370).
6. Derate linearly above 70°C free-air temperature at a rate of 3.9 mW/°C (HCPL-3700/3760) and 1.9 mW/°C (HCPL-0370). Maximum output
power dissipation of 210 mW (HCPL-3700/3760) and 103 mW (HCPL-0370) allows an output IC junction temperature of 125°C at an ambient
temperature of TA = 70°C.
7. Derate linearly above 70°C free-air temperature at a rate of 0.6 mA/°C.
8. Maximum operating frequency is defined when output waveform Pin 6 obtains only 90% of VCC with RL = 4.7 kW, CL = 30 pF using a 5 V square
wave input signal.
9. All typical values are at TA = 25°C, VCC = 5.0 V unless otherwise stated.
10. 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 10).
11. 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 10).
12. Common mode transient immunity in Logic High level is the maximum tolerable (positive) dVCM/dt on the leading edge of the common
mode pulse, VCM, to insure 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 (negative) dVCM/dt on the trailing edge of the common mode pulse signal, VCM, to insure that the output will
remain in a Logic Low state (i.e., VO < 0.8 V). See Figure 11.
13. 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 de-
tector IC from destructively high surge currents. The recommended value for RCC is 240 ý per volt of allowable drop in VCC (between Pin 8 and
VCC) with a minimum value of 240 ý.
14. Logic low output level at Pin 6 occurs under the conditions of VIN ž 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-
.
15. AC voltage is instantaneous voltage.
16. Device considered a two terminal device: Pins 1, 2, 3, 4 connected together, and Pins 5, 6, 7, 8 connected together.
17. In accordance with UL 1577, each optocoupler is proof tested by applying an insulation test voltage ≥ 4500 V rms for 1 second (leakage
detection current limit, Ii-o ≤ 5 µA).
18. In accordance with UL 1577, each optocoupler is proof tested by applying an insulation test voltage ≥ 6000 V rms for 1 second (leakage
detection current limit, Ii-o ≤ 5 µA). This test is performed before the 100% production test for partial discharge (Method b) shown in the IEC/
EN/DIN EN 60747-5-5 Insulation Characteristics Table.

For interfacing ac signals to TTL systems, output low
pass filtering can be performed with a pullup resistor of
1.5 kW and 20 µF capacitor. This application requires a
Schmitt trigger gate to avoid slow rise time chatter prob-
lems. For ac input applications, 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

The HCPL-0370/3700/3760 optocouplers have internal
temperature compensated, predictable voltage and cur-
rent threshold points which allow selection of an exter-
nal 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 12. Specific calculation of RX can be obtained
from Equation (1). Specification of both V and V voltage

For two specifically selected external threshold voltage
levels, V+ and V-, the use of RX and RP will permit this selec-
tion via equations (2), (3) provided the following condi-
tions are met. If the denominator of equation (2) is posi-
tive, then
threshold levels simultaneously can be obtained by the
use of RX and RP as shown in Figure 13 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 of a relay or switch, the HCPL-
0370/3700/3760 in combination with RX and RP can be
used to allow a specific current to be conducted through
the contacts for cleaning purposes (wetting current).

(such as static discharge), a series resistor, RCC, should
be connected in series with VCC and Pin 8 to protect the

Note 13 for determination of RCC. In addition, it is recom-
mended that a ceramic disc bypass capacitor of 0.01 µF
be placed between Pins 8 and 5 to reduce the effect of
power supply noise.
