Note 1) VSS means AVSS, VSSBGR, DVSS, PVSSR and PVSSL. Place all VSS terminals in the same potential.

Note 2) All the voltages are measured with respect to VSS=0V.

Note 3) Power supply terminal (VDDP) means PVDDREG, PVDDPR, PVDDMR, PVDDPL and PVDDML.

Note 4) Control Input/Output terminal means MUTEN, HP, VOL[1:0] and MODE[2:0].

Note 5) Input/output terminal means INL, VREFL, INR, VREFR, XI and XO.

Note 6) Absolute Maximum Ratings is values which must not be exceeded to guarantee device reliability and life,

and when using a device in excess even a moment, it may immediately cause damage to device or may

significantly deteriorate its reliability
