Agilent HCPL-270L/ 070L/273L/073L
Low Input Current High Gain
LVTTL/LVCMOS Compatible
3.3 V Optocouplers
Data Sheet
Description
These high gain series couplers use
a Light Emitting Diode and an
integrated high gain photodetector
to provide extremely high current
transfer ratio between input and
output. Separate pins for the
photodiode and output stage result
in LVTTL compatible saturation
voltages and high speed operation.
Where desired, the VCC and VO
terminals may be tied together to
achieve conventional photo-
darlington operation. A base
access terminal allows a gain
bandwidth adjustment to be
made.
These optocouplers are for use in
LVTTL/LVCMOS or other low
power applications. A 400%
minimum current transfer ratio is
guaranteed over 0 to +70˚C
operating range for only 0.5 mA
of LED current.
