CAUTION: It is advised that normal static precautions be taken in handling and assembly of this component to
prevent damage and/or degradation which may be induced by ESD.
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
configuration 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
µA
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
conventional 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
µA
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.
