ACPL-772L and ACPL-072L
3.3V/5V High Speed CMOS Optocoupler
Data Sheet
Description
Available in either an 8-pin DIP or SO-8 style respectively,
the ACPL-772L or ACPL-072L optocouplers utilize the
latest CMOS IC technology to achieve outstanding speed
performance of minimum 25MBd data rate and 6ns
maximum pulse width distortion.
Basic building blocks of this family of products are a
CMOS LED driver IC, a high speed LED and a CMOS
detector IC. A CMOS logic input signal controls the LED
driver IC, which supplies current to the LED. The detector
IC incorporates an integrated photodiode, a high speed
transimpedance amplifier, and a voltage comparator with
an output driver.
