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.
Description
The HCPL-2602/12 are optically coupled line receivers
that combine a GaAsP light emitting diode, an input
current regulator and an integrated high gain photo
detector. The input regulator serves as a line
termination for line receiver applications. It clamps
the line voltage and regulates the LED current so line
reflections do not interfere with circuit performance.
The regulator allows a typical LED current of 8.5 mA
before it starts to shunt excess current. The output
of the detector IC is an open collector Schottky clamped
transistor. An enable input gates the detector. The
internal detector shield provides a guaranteed
common mode transient immunity specification of
1000 V/ms for the 2602, and 3500 V/ms for the 2612.
DC specifications are defined similar to TTL logic.
The optocoupler ac and dc operational parameters
are guaranteed from 0
°C to 70°C allowing trouble-
free interfacing with digital logic circuits. An input
current of 5 mA will sink an eight gate fan-out (TTL)
at the output.
