† _{All typical values are at VCC = 5 V, TA = 25°C.}
‡ _{This parameter approximates IOS. The condition VO = 0.5 V takes tester noise into account. Not more than one output should be shorted at a}
time and duration of the short circuit should not exceed one second.
§ _{See the fmax calculations section.}
¶ _{The active edge of CLK is determined by the programmed state of the CLK polarity fuse.}
# _{tpd CLK to Q (nonregistered) is the same for data clocked from the counter or state registered.}
NOTE 4: When the clock is programmed for negitive edge, then VI = 4.5 V. When the clock is programmed for positive edge, then VI = 0.
