AC Timing Characteristics — 5V Operation AT40K
Delays are based on fixed loads and are described in the notes.
Maximum times based on worst case: V_CC = 4.75V, temperature = 70C
Minimum times based on best case: V_CC = 5.25V, temperature = 0C
Maximum delays are the average of t_PDLH and t_PDHL.
Clocks and Reset Input buffers are measured from a V_IH of 1.5V at the input pad to the internal V_IH of 50% of V_CC.
Maximum times for clock input buffers and internal drivers are measured for rising edge delays only.
