*Stresses greater than those listed under “Absolute Maxi-
mum Ratings” may cause permanent damage to the de-
vice. This is a stress rating only and functional operation
of the device at these or any other conditions above those
indicated in the operational sections of this specification
is not implied. Exposure to absolute maximum rating
conditions for extended periods may affect reliability.
**Maximum DC voltage on V
for periods < 20ns.
