Broadcom HCPL-7721

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.
