Electrical Characteristics
The data in this chapter is pre-qualification and pre-characterization and is subject to
change. Additional electrical characteristics may be found in the individual chapters.
Absolute Maximum Ratings
Stresses greater than those listed in
may cause permanent damage to the device.
These ratings are stress ratings only. Operation of the device at any condition outside those
indicated in the operational sections of these specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
For improved reliability, tie unused inputs to one of the supply voltages (V
DD
or V
SS
).
