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.
The HCPL-0370/3700's input
buffer IC has a nominal turn on
threshold of 2.5 mA (ITH +) and
3.7 volts (V +).
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 industrial control
computer input boards and other
applications where a predeter-
mined input threshold level is

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.
