ACPL-K72T-000E

High Speed CMOS R²Coupler with AEC-Q100 Grade 1 Qualification

Currently Viewing:

The ACPL-K71T and ACPL-K72T are high speed digital CMOS optocouplers  in packages suitable for emerging electric vehicle applications. The ACPL-K74T and ACPL-K75T are dual channel equivalent of the ACPL-K71T and ACPL-K72T respectively. All products are available in the stretched SO-8 package outline, designed to be compatible with surface mount processes.

ACPL-K71T and ACPL-K74T feature high speed mode with fastest propagation delay (max. 35ns at IF = 10mA) while ACPL-K72T and ACPL-K75T are low power mode with lowest LED drive current of 4mA for standard digital isolation switching.

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.

Broadcom R2Coupler provides with reinforced insulation and reliability that delivers safe signal isolation critical in automotive and high temperature industrial applications.
