Description
The ACFL-6211T and ACFL-6212T are automotive grade
dual channel, bi-directional, high speed digital CMOS op-
tocouplers. The stretched SO-12 stretched package out-
line is designed to be compatible with standard surface
mount processes and occupies the same land area as their
single channel equivalent, ACPL-K71T and ACPL-K72T, 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 out-
put. 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 insula-
tion and reliability that delivers safe signal isolation criti-
cal in automotive and high temperature industrial appli-
cations.
