This device contains protective circuitry against damage due to high static voltages or
electrical fields; however, it is advised that normal precautions be taken to avoid applica-
tion of any voltages higher than maximum-rated voltages to this high-impedance circuit.
Reliability of operation is enhanced if unused inputs are tied to an appropriate logic volt-
age level (e.g., either GND or V
CC
).
Figure 5.
Clock Input Timing Diagram
Note:
Timing measurements are referenced to and from a low voltage of 0.8V and a high volt-
age of 2.0V, unless otherwise noted. The voltage swing through this range should start
outside and pass through the range such that the rise or fall will be linear between 0.8V
and 2.0V.

For most applications P

and can be neglected.
An approximate relationship between P

and T

(if P
