• Manufacturer: ATMEL [ATMEL Corporation]

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
Minimum times based on best case: V
Maximum delays are the average of t
All input IO characteristics measured from a V
of V
All input IO characteristics measured from a V
output IO characteristics are measured as the average of t
