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

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.

• 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
