HCPL-2602/2612 High CMR Line Receiver Optocouplers
Data Sheet
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 guara...
