Data Sheet
Description
The ACPL-K71T and ACPL-K72T are high-speed digital CMOS
optocouplers package suitable for emerging electric vehicle
applications. The ACPL-K74T and ACPL-K75T are dual-channel
equivalents of the ACPL-K71T and ACPL-K72T, respectively. All
products are available in the stretched SO-8 package outline,
designed to be compatible with standard surface mount
processes.
ACPL-K71T and ACPL-K74T are high-speed mode with fastest
propagation delay (maximum 35 ns at I_F = 10 mA) while
ACPL-K72T and ACPL-K75T are low-power mode with lowest
LED drive current of 4 mA 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.
The Broadcom R²Coupler® provides with reinforced insulation
and reliability that delivers safe signal isolation critical in
automotive and high-temperature industrial applications.
