Description
The HCPL-3700 and HCPL-3760
are voltage/current threshold
detection optocouplers. The
HCPL-3760 is a low-current
version of the HCPL-3700. To
obtain lower current operation,
the HCPL-3760 uses a high-
efficiency AlGaAs LED which
provides higher light output at
lower drive currents. Both
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.
Functional Diagram
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
Applications
• Limit Switch Sensing
• Low Voltage Detector
• 5 V-240 V AC/DC Voltage
