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 Di-
ode and an integrated high gain photodetector to pro-
vide extremely high current transfer ratio between input
and output. Separate pins for the photodiode and out-
put 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 al-
lows 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 de-
vices 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 foot-
print area of the standard dual-in-line package. The lead
profile is designed to be compatible with standard sur-
face mount processes.
