4/4 rev. b application example (1) numbers and data in entries are r epresentative design values an d are not guaranteed values of the items. (2) although we are confident in recommending the sample applicatio n circuits, carefully check their characteristics further when usin g them. when modifying extern ally attached component constants before use, determine them so that they have sufficient margins by tak ing into account variations in externally attached components and the rohm lsi, not only for static chara cteristics but also including transient characteristics. (3) absolute maximum ratings if applied voltage, operating temperature range, or other absol ute maximum ratings are exceeded, the lsi may be damaged. do not apply voltages or temperatures that exc eed the absolute maximum ratings. if you think of a case in which absolute maximum ratings are excee ded, 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. (4) gnd potential make the gnd pin voltage such that it is the lowest voltage eve n when operating below it. actually confirm that the voltage of each pin does not become a lower voltage th an the gnd pin, including transient phenomena. (5) thermal design perform thermal design in which there are adequate margins by t aking into account the allowable power dissipation in actual states of use. (6) shorts between pins and misinstallation when mounting the lsi on a board, pay adequate attention to ori entation 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 ls i or between a pin and a power supply or a pin and a gnd. (7) operation in strong magnetic fields adequately evaluate use in a strong magnetic field, since there is a possibility of malfunction.
