Description
The HCPL-260L/060L/263L/063L are optically coupled
gates that combine a GaAsP light emitting diode and
an integrated high gain photo detector. An enable in-
put allows the detector to be strobed. The output of
the detector IC is an open collector Schottky-clamped
transistor. The internal shield provides a guaranteed
common mode transient immunity specication of
15 kV/µs at 3.3V.
This unique design provides maximum AC and DC circuit
isolation while achieving LVTTL/LVCMOS compati-bili-
ty. The optocoupler AC and DC operational parameters
are guaranteed from –40 °C to +85 °C allowing trouble-
free system performance.
These optocouplers are suitable for high speed logic
interfacing, input/output buering, as line receivers in
environments that conventional line receivers cannot
tolerate and are recommended for use in extremely high
ground or induced noise environments.
