This is a stress Parameter Rating rating only; functional operation of the device at these or any VDD to GND −0.3 V to +7 V other conditions above those indicated in the operational Digital Input Voltage to GND −0.3 V to VDD + 0.3 V section of this specification is not implied. Exposure to absolute Digital Output Voltage to GND −0.3 V to VDD + 0.3 V maximum rating conditions for extended periods may affect Reference Input Voltage to GND −0.3 V to VDD + 0.3 V device reliability.
