Notes

1 All voltages are with respect to GND.

2 This is a stress rating only and functional operation of the device at these or any other conditions

beyond those indicated in the operating sections of this specification is not implied. Stresses

greater than those listed may cause permanent damage to the device. Exposure to absolute

maximum rating conditions for extended periods may affect reliability.

3 This device contains circuitry to protect the inputs against damage caused by high static voltages

or electrical fields. However, it is advised that normal precautions be taken to avoid application

of any voltage higher than the absolute maximum rated voltages to this high impedance circuit.

Unused inputs should be tied to an appropriate logic level such as VDD or GND.

4 The input current applies to any input or output pin and applies when the voltage on the pin is

between GND and VDD.
