DataSheet  
Description  
Features  
TheHCPL-2602/12areopticallycoupledlinereceivers  
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.  
• 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)  
The regulator allows a typical LED current of 8.5 mA  
before it starts to shunt excess current. The output

Guaranteed AC and DC performance over temperature:  
0°C to 70°C  
transistor. An enable input gates the detector. The External base lead allows “LED peaking” and LED  
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.  
current adjustment  
• Safety approval  
UL recognized – 3750 V rms for 1 Minute  
CSA approved  
DC specifications are defined similar to TTL logic.  
The optocoupler ac and dc operational parameters  
are guaranteed from 0°C to 70°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.  
• MIL-PRF-38534 hermetic version available (HCPL-1930/ 1)  
Applications  
• Isolated line receiver  
Computer-peripheral interface  
• Microprocessor system interface  
Digital isolation for A/ D, D/ A conversion  
Current sensing  
• Instrument input/ output isolation  
Ground loop elimination  
• Pulse transformer replacement  
• Power transistor isolation in motor drives
