HCPL-2602 - High CMR Line Receiver Optocouplers

General 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.

Key Features

  • 1000 V/µs minimum Common Mode Rejection (CMR) at VCM = 50 V for HCPL-2602 and 3.5 kV/µs minimum CMR at VCM = 300 V for HCPL-2612.
  • Line termination included.
  • no extra circuitry required.
  • Accepts a broad range of drive conditions.
  • LED protection minimizes LED efficiency degradation.
  • High speed: 10 MBd (limited by transmission line in many.

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.
