Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device.
These are stress ratings only and functional operation of the device at these or any other conditions beyond those
indicated in the operational sections of the specifications are not implied. Exposure to absolute maximum rating
conditions for extended periods may affect device reliability.
ELECTRICAL SPECIFICATIONS
Unless otherwise specified, these specifications apply: VDD = 3.3V ± 5%, 0 o C ≤ T J ≤ 125 o C, 0.5 ≤ Vo ≤ 1.8 V, and
operation in the typical application circuit. See notes following table.
