Description
The HCPL-0370/3700 and
HCPL-3760 are voltage/current
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-efficiency AlGaAs LED
which provides higher light
output at lower drive currents.
The devices utilize threshold
sensing 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 diode
bridge for easy use with ac input
signals, and internal clamping

*The Input-Output Momentary Withstand Voltage is a dielectric voltage rating that should not be interpreted as an input-output
continuous voltage rating. For the continuous voltage rating refer to the IEC/EN/DIN EN 60747-5-2 Insulation Characteristics Table (if
applicable), your equipment level safety specification, or Agilent Application Note 1074, “Optocoupler Input-Output Endurance Voltage.”
