DC Electrical Characteristics
(Continued)
Note 4:
Outputs disabled or 3-STATE only.
Note 5:
An external driver must source at least the specified current to switch from LOW-to-HIGH.
Note 6:
An external driver must sink at least the specified current to switch from HIGH-to-LOW.
AC Electrical Characteristics
Note 7:
Skew is defined as the absolute value of the difference between the actual propagation delay for any two separate outputs of the same device. The
specification applies to any outputs switching in the same direction, either HIGH-to-LOW (t
OSHL
) or LOW-to-HIGH (t
OSLH
).
