Notes:
1. Test load, see Figure 5.
2. Capacitance is periodically sampled rather than 100% tested.

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 of fall will be linear between 0.8V
and 2.0V.
