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.
