Description
The ACFL-5211T is an automotive grade 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 single channel
equivalent, ACPL-K43T, in 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 auto-
motive and high temperature industrial applications
