Description
These devices are very low power
consumption, high gain single
and dual channel optocouplers.
The HCPL-4701 represents the
single channel 8-Pin DIP configu-
ration and is pin compatible with
the industry standard 6N139. The
HCPL-4731 represents the dual
channel 8-Pin DIP configuration
and is pin compatible with the
popular standard HCPL-2731.
The HCPL-070A and HCPL-073A
are the equivalent single and dual
channel products in an SO-8
footprint. Each channel can be
driven with an input current as
low as 40
A and has a typical
current transfer ratio of 3500%.
These high gain couplers use an
AlGaAs LED and an integrated
high gain photodetector to
provide an extremely high
current transfer ratio between
input and output. Separate pins
for the photodiode and output
stage results in TTL compatible
saturation voltages and high
speed operation. Where desired,
the V
CC
and V
O
terminals may be
tied together to achieve conven-
tional Darlington operation
(single channel package only).
These devices are designed for
use in CMOS, LSTTL or other low
power applications. They are
especially well suited for ISDN
telephone interface and battery
operated applications due to the
low power consumption. A 700%
minimum current transfer ratio is
guaranteed from 0
C to 70
C
operating temperature range at
40
A of LED current and
V
CC
3 V.
The SO-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.
