ACFL-5211U Datasheet, PDF (1/13 Pages) AVAGO TECHNOLOGIES LIMITED – Bi-directional Wide Operating Temperature 1MBd Digital
ACFL-5211U
Bi-directional Wide Operating Temperature 1MBd Digital
Optocoupler with R2CouplerTM Isolation in a Stretched 12-Pin
Surface Mount Plastic Package
Data Sheet
Description
The ACFL-5211U is a dual channel, bi-directional, high speed
1MBd digital optocoupler. The stretched SO-12 stretched
package outline is designed to be compatible with standard
surface mount processes and occupies the same land area as
the stretched SO8 package.
This digital optocoupler uses an insulating layer between the
light emitting diode and an integrated photo detector to
provide electrical insulation between input and output. Each
channel is also galvanically isolated from the other with no
cross-talk.
Avago R2Coupler provides with reinforced insulation and
reliability that delivers safe signal isolation critical in high
temperature industrial applications.
