NOTES:
1. Absolute maximum rating specifies the values beyond which the device may be damaged permanently. Exposure
to absolute maximum rating conditions for extended periods may affect reliability. Each condition value is applied
with the other values kept within the following operating conditions and function operation under any of these conditions
is not implied.
2.
All voltages are measured with respect to VSS(AVSS12A or AVSS12D or AVBB) unless otherwise specified.
3.
100pF capacitor is discharged through a 1.5k
resistor (Human body model)

NOTE: It is strongly recommended that to avoid power latch-up all the supply pins(AVDD12A, AVDD12D) be driven from
the
same source.
