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.
