AC Timing
Characteristics
Delays are based on fixed loads which are described in the notes.
Maximum timing based on worst case: V
Minimum timing based on best case: V
Maximum delays are the average of t
AC Timing
Characteristics
All input I/O characteristics measured from V
All output I/O characteristics are measured as the average of t
