Notes :
(1)Stresses above those listed may cause permanent damage to the
device. 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 device reliability.
(2) Pulse width:- 3.0V for less than 10ns.
