Agilent HCPL-260L/ 060L/263L/063L
High Speed LVTTL Compatible
3.3 Volt Optocouplers
Data Sheet
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 input
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
specification of 15 kV/ µs.
This unique design provides
maximum AC and DC circuit
isolation while achieving
LVTTL/LVCMOS compatibility.
The optocoupler AC and DC
operational parameters are
guaranteed from –40˚C to +85˚C
allowing trouble-free system
performance.
