Note: This product has a MOS structure and is sensitive to electrostatic discharge. When handling this product, ensure that the environment is protected against electrostatic discharge by using an earth strap, a conductive mat and an ionizer. Ensure also that the ambient temperature and relative humidity are maintained at reasonable levels. The IC should be installed correctly. Otherwise, the IC or peripheral parts and devices may be degraded or permanently damaged.
