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 V
CC
and V
O
terminals may be tied together to
achieve conventional photo-

made.
These optocouplers are for use in
LVTTL/LVCMOS or other low

minimum current transfer ratio is
guaranteed over 0 to +70C
operating range for only 0.5 mA

Schematic
The HCPL-070L and HCPL-073L
are surface mount devices
packaged in an industry standard
SOIC-8 footprint.
The SOIC-8 does not require
"through holes" in a PCB. This
package occupies approximately
one-third the footprint area of the
standard dual-in-line package.
The lead profile is designed to be
compatible with standard surface
mount processes.
