HCPL-270L/070L/273L/073L
Low Input Current, High Gain, LVTTL/LVCMOS Compatible 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
V
CC
and V
O
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.
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.
