Agilent HCPL-0738 High Speed CMOS Optocoupler Data Sheet Description The HCPL-0738 is a dual-channel 15 MBd CMOS optocoupler in SOIC-8 package. The HCPL-0738 optocoupler utilizes the latest CMOS IC technology to achieve outstanding performance with very low power consumption. Basic building blocks of HCPL-0738 are high speed LEDs and CMOS detector ICs. Agilent also offers the same performance in the single channel version, HCPL-0708. Each detector incorporates an integrated photodiode, a high speed transimpedance amplifier, and a voltage comparator with an output driver.
