Description
Features
The HCPL-0370/3700 and HCPL-3760 are voltage/
currentthresholddetectionoptocouplers.TheHCPL-
3760 is a low-current version of the HCPL-0370/
3700. To obtain lower current operation, the HCPL-
3760 uses a high-efficiency AlGaAs LED which
provides higher light output at lower drive currents.
ThedevicesutilizethresholdsensinginputbufferICs
which permit control of threshold levels over a wide
rangeofinputvoltageswithasingleexternalresistor.
• Standard (HCPL-0370/ 3700) and low input current
(HCPL-3760) versions
• AC or DC input
• Programmable sense voltage
• Hysteresis
• Logic compatible output
• Thresholds guaranteed over temperature
• Thresholds independent of LED optical parameters
• Recognized under UL 1577 and CSA approved for
dielectric withstand proof test voltage of 3750 Vac,
1 minute
The input buffer incorporates several features:
hysteresis for extra noise immunity and switching
immunity, a diode bridge for easy use with ac input
signals, and internal clamping diodes to protect the
buffer and LED from a wide range of over-voltage and
over-currenttransients.Becausethresholdsensingis
done prior to driving the LED, variations in optical
coupling from the LED to the detector will have no
effect on the threshold levels.
Applications
• Limit switch sensing
• Low voltage detector
• 5 V-240 V AC/ DC voltage sensing
• 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 high gain output stage
computer input boards and other
applications where a predeter-
mined input threshold level is
desirable.
features an open collector output
providing both TTL compatible
saturation voltages and CMOS
compatible breakdown voltages.
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 +).
By combining several unique
functions in a single package, the
user is provided with an ideal
component for industrial control
Ordering Information
HCPL-0370/HCPL-3700/HCPL-3760 is UL Recognized with 3750 Vrms for 1 minute per UL1577 unless

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 temperature of
TA = 70°C. Excessive PIN and T may result in IC chip degradation.
J
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 kΩ, 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) dV / dt on the leading edge of the common mode pulse,
CM
V , to insure that the output will remain in a Logic High state (i.e., V > 2.0 V). Common mode transient immunity in Logic Low level is the maximum
CM
O
tolerable (negative) dV / dt on the trailing edge of the common mode pulse signal, V , to insure that the output will remain in a Logic Low state
CM
CM
(i.e., V < 0.8 V). See Figure 11.
O
13. In applications where dV / dt may exceed 50,000 V/ µs (such as static discharge), a series resistor, RCC, should be included to protect the detector IC
CM
from destructively high surge currents. The recommended value for RCC is 240 Ω per volt of allowable drop in VCC (between Pin 8 and V ) with a

Electrical Considerations
The low clamp condition in
conjunction with the low input
current feature will ensure
extremely low input power
dissipation.
For one specifically selected
external threshold voltage level V
The HCPL-0370/3700/3760
optocouplers have internal
temperature compensated,
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

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
high surge currents. See Note 13
for determination of RCC. In addi-
tion, it is recommended that a
ceramic disc bypass capacitor of
0.01 µF be placed between Pins 8
and 5 to reduce the effect of

For two specifically selected
external threshold voltage levels,
V+ and V-, the use of RX and RP
will permit this selection via
equations (2), (3) provided the
following conditions are met. If
the denominator of equation (2) is
positive, then
typical value of RX can be ob-
tained from Figure 12. Specific
calculation of RX can be obtained
from Equation (1). Specification

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

RX can provide over-current
transient protection by limiting
input current during a transient
condition. For monitoring con-
tacts 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).

Either ac (Pins 1, 4) or dc (Pins 2,

external threshold levels.
The choice of which input voltage
clamp level to choose depends
upon the application of this
device (see Figure 1). It is recom-
mended that the low clamp
