8.0 SPECIFICATIONS
8.1 ABSOLUTE MAXIMUM RATINGS
Stresses greater than those listed in this table may cause permanent damage to the device.
Precautions should be taken to avoid application of any voltage higher than the maximum rated
voltages to this circuit. Subjection to maximum conditions for extended periods may affect reliability.
Unused inputs must always be tied to an appropriate logic voltage level (Ground or Vdd).
