Description
Avago’s ACPL-077L optocoupler utilizes the latest CMOS
IC technology to achieve outstanding speed and low
power performance of minimum 25 MBd data rate and
6 ns maximum pulse width distortion with enhanced
reliability relative to system level IEC 61000-4-X testing
(ESD/Burst/Surge).
Available in SO-8 package, the basic building blocks of
ACPL-077L 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 compara-
tor with an output driver.
