Data Sheet HCPL-0720, HCPL-7720, HCPL-0721, and HCPL-7721 40-ns Propagation Delay, CMOS Optocoupler Description Features Available in either an 8-pin DIP or SO-8 package style +5V CMOS compatibility respectively, the Broadcom HCPL-772X or HCPL-072X 20-ns max propagation delay skew optocouplers utilize the latest CMOS IC technology to High speed: 25 MBd achieve outstanding performance with very low power 40-ns max propagation delay consumption. The HCPL-772X/072X require only two 10-kV/s minimum common mode rejection bypass capacitors for complete CMOS compatability. 40 to +85C temperature range Safety and regulatory approvals: Basic building blocks of the HCPL-772X/072X are a CMOS UL recognized LED driver IC, a high-speed LED, and a CMOS detector IC. 3750 V for 1 min. per UL 1577 A CMOS logic input signal controls the LED driver IC, which rms supplies current to the LED. The detector IC incorporates an 5000 V for 1 min. per UL 1577 (for HCPL-772X rms option 020) integrated photodiode, a high-speed transimpedance amplifier, and a voltage comparator with an output driver.
