Note 1:

Functional operation above the absolute maximum stress ratings is not implied.

Note 2:

Static-sensitive device. Store only in conductive containers. Handling personnel and equipment should be grounded to

prevent damage from static discharge.

Note 3:

Switching times guaranteed by design.
