4. All limits at temperature extremes are guaranteed via correlation using standard Statistical Quality Control (SQC).
5. AC specifications are guaranteed by characterization, but not production tested.
6. For propagation delays, “tpdh’’ refers to the specified signal going high; “tpdl’’ refers to it going low.
7. GBD: Guaranteed by design; not tested in production.
Specifications subject to change without notice.
