■Cautions on use
(1) Numbers and data in entries are representative design values and are not guaranteed values of the items.
(2) Absolute maximum ratings
If applied voltage, operating temperature range, or other absolute maximum ratings are exceeded, the LSI may
be damaged. Do not apply voltages or temperature s that exceed the absolute maximum ratings, If you think of a
case in which absolute maximum ratings are exceeded, enforce fuses or other physical safety measures and
investigate how not to apply the conditions under which absolute maximum ratings are exceeded to the LSI.
(3) GND potential
Make the GND pin voltage such that it is the lowest voltage even when operating below it. Actually confirm that the
voltage of each pin does not become a lower voltage than the GND pin, including transient phenomena. Absolute
maximum ratings.
(4) Thermal design
Perform thermal design in which there are adequate margins by taking into account the allowable power
dissipation in actual states of use.GND potential
Make the GND pin voltage such that it is the lowest voltage even when operating below it. Actually confirm that
the voltage of each pin does not become a lower voltage than the GND pin, including transient phenomena.
(5) shorts between pins and misinstallation
When mounting the LSI on a board, pay adequate attention to orientation and placement discrepancies of the LSI.
If it is misinstalled and the power is turned on, the LSI may be damaged. It also may be damaged if it is shorted by
a foreign substance coming between pins of the LSI or between a pin and a power supply or a pin a GND.
(6) Operation in strong magnetic fields
Adequately evaluate use in a strong magnetic field, since there is a possibility of malfunction.
