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 Range1 −40°C to +150°C maximum rating conditions for extended periods may affect Storage Temperature Range −65°C to +150°C device reliability.
