AC Electrical Characteristics
74FR74
Note 3:
Pin-to-Pin Skew is defined as the absolute value of the difference between the actual propagation delay for any outputs within the same packaged
device. The specifications apply to any outputs switching in the same direction either HIGH-to-LOW (t
OSHL
) or LOW-to-HIGH (t
OSLH
) or in opposite directions
both HL and LH (t
OST
). t
OST
is guaranteed by design.
