† 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.
