(2)gnd potential maintain the gnd pin at the minimum voltage even under any oper ating conditions. actually check to be sure that none of the pins have voltage lo wer than that of gnd pin, including transient phenomena. (3)thermal design with consideration given to the permissible dissipation under a ctual use conditions, perform thermal design so that adequate m argins will be provided. (4)short circuit between pins and malfunctions to mount the lsi on a board, pay utmost attention to the orient ation and displacement of the lsi. faulty mounting to apply a voltage to the lsi may cause damage to the lsi. furthermore, the lsi m ay 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 magnet ic field. not doing so may malfunction the lsi. vcsp85h2 lot no. 24020 mgnd34 out4b out4a mvcc34 out3a mgnd12 dvss sclk piout2 out3b out1b state1 test sdata dvdd piout1 state2 csb sout out1a mvcc12 out2a out2b fclk e d c b 45 a 123
