Description
Available in either an 8-pin DIP or SO-8 package style
respectively, the HCPL-772X or HCPL-072X optocouplers
utilize the latest CMOS IC technology to achieve out-
standing performance with very low power consump-
tion. The HCPL-772X/072X require only two bypass ca-
pacitors for complete CMOS compatability.
Basic building blocks of the HCPL-772X/072X 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 incor-
porates an integrated photodiode, a high-speed tran-
simpedance amplifier, and a voltage comparator with an
output driver.

for guaranteed data sheet performance. Pin 7 is not connected
internally.
