2.8 AC Specifications

This section describes the AC specifications for the

80960MC pins. All input and output timings are spec-

ified 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 VCC.
