Parameter Rating
may cause permanent damage to the device. This is a stress V to GND −0.3 V to +7 V DD rating only; functional operation of the device at these or any Digital Input Voltage to GND −0.3 V to V + 0.3 V DD other conditions above those indicated in the operational Digital Output Voltage to GND −0.3 V to V + 0.3 V DD section of this specification is not implied. Exposure to absolute Operating Temperature Range −40°C to +125°C maximum rating conditions for extended periods may affect Storage Temperature Range −65°C to +150°C device reliability.

Refer to Figure 3 for a plot of maximum power dissipation vs. ambient temperature (TA). 2 T A = ambient temperature. 3 Junction-to-case resistance is applicable to components featuring a preferential flow direction, for example, components mounted on a heat sink. Junction-to-ambient resistance is more useful for air-cooled, PCB- mounted components. Rev.
