LOGIC DIAGRAM

Notes:

1. Logic will not latchup during radiation exposure within the limits defined in the table

2. Device storage elements are immune to SEU affects.

ABSOLUTE MAXIMUM RATINGS

Note:

1. Stresses outside the listed absolute maximum ratings may cause permanent damage to the device. This is a stress rating only, functional operation of the device

at these or any other conditions beyond limits indicated in the operational sections is not recommended. Exposure to absolute maximum rating conditions for

extended periods may affect device reliability.
