Description
Available in either 8-pin DIP or SO-8 package style respec-
tively, the HCPL-7723 or HCPL-0723 optocoupler utilize
the latest CMOS IC technology to achieve out standing
speed performance of minimum 50 MBd data rate and
2 ns maximum pulse width distortion.
Basic building blocks of HCPL-7723/0723 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 amplier, and a voltage comparator with
an output driver.
