Data Sheet
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 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.
