High Speed CMOS Optocoupler

Currently Viewing:

Available in SO-8 package, the HCPL-0708 high speed optocoupler utilizes the latest CMOS IC technology to achieve outstanding performance with very low power consumption. Basic building blocks of the HCPL-0708 are a high speed LED and a CMOS detector IC. The detector incorporates an integrated photodiode, a high-speed trans-impedence amplifier, and a voltage comparator with an output driver.
