Do not apply voltages or temperatures that exceed the absolute maximum ratings. If you expect that any voltage or temperature could be exceeding the absolute maximum ratings, take physical safety measures such as fuses to prevent any conditions exceeding the absolute maximum ratings from being applied to the LSI. (2)GND potential Maintain the GND pin at the minimum voltage even under any operating conditions. Actually check to be sure that none of the pins have voltage lower than that of GND pin, including transient phenomena. (3)Thermal design With consideration given to the permissible dissipation under actual use conditions, perform thermal design so that adequate margins will be provided. (4)Short circuit between pins and malfunctions To mount the LSI on a board, pay utmost attention to the orientation and displacement of the LSI. Faulty mounting to apply a voltage to the LSI may cause damage to the LSI. Furthermore, the LSI may also be damaged if any foreign matters enter between pins, between pin and power supply, or between pin and GND of the LSI. (5)Operation in strong magnetic field Make a thorough evaluation on use of the LSI in a strong magnetic field. Not doing so may malfunction the LSI. REV.
