Terminals of TA8428 written below are 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.
Terminals which are sensitive to electrostatic discharge: No. 1 and 2 (TA8428K）, No. 8 and 9 (TA8428FG)
The IC should be installed correctly. Otherwise, the IC or peripheral parts and devices may be degraded or permanently
damaged.
