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/µs for the 2602, and
3500 V/µs 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 trouble-free
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.
