Description
The HCPL-0370/3700 and HCPL-3760 are voltage/cur-
rent threshold detection optocouplers. 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
lower drive currents. The devices utilize threshold sens-
ing input buffer ICs which permit control of threshold
levels over a wide range of input voltages with a single
external resistor.
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.

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 (I
TH
+) and 3.7 volts (V
TH
+).
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 (I
TH
+) and 3.7 volts (V
TH
+).
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
