ACFL-6211U Datasheet, PDF (1/13 Pages) AVAGO TECHNOLOGIES LIMITED – Compact, auto-insertable stretched SO12 packages
ACFL-6211U, ACFL-6212U
Bi-directional High Speed, Low Power Digital Optocoupler
with R2CouplerTM Isolation in a Stretched 12-Pin
Surface Mount Plastic Package
Data Sheet
Description
The ACFL-6211U and ACFL-6212U are dual channel,
bi-directional, high speed digital CMOS optocouplers. The
stretched SO-12 stretched package outline is designed to be
compatible with standard surface mount processes and
occupies the same land area as their single channel 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 of the digital optocoupler has a CMOS detector IC
with an integrated photodiode, a high speed trans-impedance
amplifier, and a voltage comparator with an output driver. Each
channel is also isolated from the other.
Avago R2Coupler technology provides reinforced insulation
and reliability that delivers safe signal isolation critical in high
temperature industrial applications.
