NOTES
1Tested at VCC = 4 5 V, 5.0 V and 5.5 V.
Specifications shown in boldface are tested on all production units at final electrical test. Results from those tests are used to calculate outgoing quality levels. All min and max specifications
are guaranteed although only those shown in boldface are tested on all production units.
Specifications subject to change without notice.
