Absolute Maximum DC Power Supply Rating - The failure mode is non-catastrophic for Vdd of up to 7 volts, but will cause reduced
operating life time. The additional stress caused by higher local electric fields within the CMOS circuitry may induce metal migration,
oxide leakage and other time/quality related issues.

In order to calculate the junction temperature you must first empirically determine the current draw (total Idd) for the design. Once the
current consumption established then the following formula can be used; Tj = Ta + Idd x Vdd x 55 °C/W, where Ta is the ambient
temperature. The worst case
θ
ja of 55 °C/W assumes no air flow and no additional heatsink of any type.
