(2) recommended operating range this is the range within which it is possible to obtai n roughly the expected characteristics. for electrical characteristics, it is thos e that are guaranteed under the conditions for ea ch parameter. even when these are within the recommended operating range, voltage and te mperature characteristics are indicated. (3) reverse connection of power supply connector there is a risk of damaging the lsi by reverse connection of t he power supply connector. for protection from reverse connection, take measures such as externally placing a diode between the power supply and the power supply pin of the lsi. (4) power supply lines in the design of the board pattern, make power supply an d gnd line wiring low impedance. when doing so, although the digital power supply and analog power supply are the same potential, separate the digital power supply pattern and analog power supply pattern to deter digital noise from entering the analog power supply due to the common impedance of the wiring patterns. similarly take pattern desi gn into account for gnd lines as well. furthermore, for all power supply pins of the lsi, in conjunction with insert ing capacitors between power supply and gnd pins, when using electrolytic capacitors, determine constants upon adequa tely confirming that capacitance loss occurring at low temperatures is not a problem for various characteristics of the capacitors used. (5) gnd voltage make the potential of a gnd pin such t hat it will be the lowest potential ev en if operating below that. in addition, confirm that there are no pins for wh ich the potential becomes less than a g nd by actually including transition phenomena. (6) shorts between pins and misinstallation when installing in the set board, pay adequate attention to ori entation and placement discrepancies of the lsi. if it is installed erroneously, there is a risk of lsi damage. there also is a risk of damage if it is shorted by a foreign substance getting between pins or between a pin and a power supply or gnd. (7) operation in strong magnetic fields be careful when using the lsi in a strong magnetic field, since it may malfunction. (8) inspection in set board when inspecting the lsi in the set board, since there is a risk of stress to t he lsi when capacitors are connected to low impedance lsi pins, be sure to discharge for each process. moreover, when getting it on and off of a jig in the inspection process, always connect it after turning off t he power supply, perform the inspection, and remove it after turning off the power supply. furthermore, as countermeas ures against static electricity, use grounding in the assembly process and take appropriate care in transport and storage. (9) input pins parasitic elements inevitably are formed on an lsi struct ure due to potential relationships. because parasitic elements operate, they give rise to interference with ci rcuit operation and may be the cause of malfunctions as well as damage. accordingly, take care not to apply a lower volt age than gnd to an input pin or use the lsi in other ways such that parasitic elements operate. moreover, do not a pply a voltage to an input pin when the power supply voltage is not being applied to the lsi. furthermore, when the power supply voltage is being applied, make each input pin a voltage less than the power supply voltage as well as within the guaranteed values of electrical characteristics. (10) ground wiring pattern when there is a small signal gnd and a large current gnd, it is recommended that you separate the large current gnd pattern and small signal gnd pattern and provide single poi nt grounding at the referenc e point of the set so that voltage variation due to resistance components of the pattern wiring and large currents do not cause the small signal gnd voltage to change. take care that the gnd wiring pattern of externally attached components also does not change. (11) externally attached capacitors when using ceramic capacitors for externally attached ca pacitors, determine constants upon taking into account a lowering of the rated capacitance due to dc bias and capa citance change due to factors such as temperature. (12) thermal design perform thermal design in which there ar e adequate margins by taking into account the permissible dissipation (pd) in actual states of use.
