2.8.
This section describes the AC specifications for the
80960KB pins. All input and output timings are
specified relative to the 1.5 V level of the rising edge
of CLK2. For output timings the specifications refer to
the time it takes the signal to reach 1.5 V.

For input timings the specifications refer to the time at
which the signal reaches (for input setup) or leaves
(for hold time) the TTL levels of LOW (0.8 V) or HIGH
(2.0 V). All AC testing should be done with input
voltages of 0.4 V and 2.4 V, except for the clock
(CLK2), which should be tested with input voltages of
0.45 V and 0.55 V
