PRELIMINARY INFORMATION

10 Switching Characteristics

The AMD-K5 processor commercial switching characteristics,

provided in Table 15 through Table 26 on page 67, are mea-

sured at the voltage levels indicated by Figure 16 on page 68.

They are measured relative to the rising edge of the CLK sig-

nal, as defined by Figure 16 through Figure 23. Output delays

are specified as a function of minimum and maximum limits,

with minimum delay times provided to external circuitry as

hold times. A synchronous input signal must be stable for cor-

rect AMD-K5 processor operation during sampling.
