ACFL-6211T, ACFL-6212T
Automotive High-Speed, Low-Power Digital
Optocoupler with R²Coupler® Isolation in a
Stretched 12-Pin Surface Mount Plastic Package
Data Sheet
Description
The ACFL-6211T and ACFL-6212T are automotive grade 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 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 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.
Broadcom R²Coupler technology provides reinforced
insulation and reliability that delivers safe signal isolation criti-
cal in automotive and high temperature industrial
applications.
