HCPL-3760
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.

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 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
