*NOTICE:

Stresses beyond those listed under “Absolute

Maximum Ratings” 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

beyond 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.

, the x 16 organization is selected. When it is connected to ground, the x 8 organization

is selected. If the ORG pin is left unconnected and the application does not load the input beyond the capability of the internal
