Overview
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 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 troublefree interfacing with digital logic circuits.
An input current of 5 mA will sink an eight gate fan-out (TTL) at the output.
The HCPL-2602/12 are useful as line receivers in high noise environments that conventional line receivers 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.
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 applications) • Guaranteed AC and DC performance over temperature: 0°C to 70°C • External base lead allows “LED peaking” and LED current adjustment • Safety approval UL recognized – 3750 V rms for 1 Minute CSA approved ...
