NQUNXIN(群芯微) 's QX0720 (single-channel) is 15 MBd CMOS optocouplers in SO-8 package. The optocouplers utilize the latest CMOS IC technology to achieve outstanding performance with very low power consumption. The basic building blocks of QX0720 are high-speed LEDs and CMOS detector ICs. Each detector incorporates an integrated photodiode, a high-speed transimpedance amplifier, and a voltage comparator with an output driver.

8. Absolute Maximum Ratings 

Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be operable above the recommended operating conditions and stressing the parts to these levels is not recommended. In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability. The absolute maximum ratings are stress ratings only.
