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 linetermination 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 3500 V/us.
DC specifications are defined similar to TTL logic. The optocoupler ac and dc operational parameters are guaranteed from 0 degrees C to 70 degrees 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.
It is useful as line receiver in high noise environments that conventional line receiver cannot tolerate. The higher LED threshold voltage provides improved immunity to differential noise and the internally shielded detector provides orders of magnitude improvement in common mode rejection with little or no sacrifice in speed.
