† Notice: Stresses above those listed under "Maximum
Ratings" may cause permanent damage to the device. This is
a stress rating only and functional operation of the device at
those or any other conditions above those indicated in the
operational sections of this specification is not intended.
Exposure to maximum rating conditions for extended periods
may affect device reliability.
DC CHARACTERISTICS (NOTE 2)
Electrical Specifications: Unless otherwise indicated, TA = +25°C, with 4.5V ≤ VDD ≤ 18V.
