ACFL-6211T

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 critical in automotive and high temperature industrial applications.
