Preliminary
19 Electrical Characteristics
19.1 DC Characteristics
19.1.1 Maximum Ratings
The maximum ratings are the limits to which the device can be subjected without permanently
damaging the device.
Note: The device is not guaranteed to operate properly at the maximum ratings.
Important: This d evice contains c ircuitry to protect the i nputs against da mage due to h igh-static
voltages or electr ic fields; however, it is adv ised that normal precautions be taken to
avoid application of any voltage higher than maximum-rated voltages to this
high-impedance circuit. Reliability of operation is enhanced if unused inputs are
connected to an appropriate logic voltage level (for example, either GND or V
DD
).
