Unless otherwise noted, all input
pulses are supplied by generators having the following characteristics:
- f = 10MHz
- ZO = 50Ω
- Δt/ΔV ≤ 1ns/V

- VCCI is
the VCC associated with the input port.
- VCCO is
the VCC associated with the output port.
- VOH and
VOL are typical output voltage levels that occur with
specified RL, CL, and S1.
- tPLH and
tPHL are the same as tpd.
- The outputs are
measured one at a time, with one transition per measurement.
