9 5 A C SPECIFICATIONS
9 5 1 A C Spec Definitions
The A C specifications given in Tables 9-4 9-5 and
9-6 consist of output delays input setup require-
ments and input hold requirements All A C specifi-
cations are relative to the CLK2 rising edge crossing
the 2 0V level
A C spec measurement is defined by Figure 9-1 In-
puts must be driven to the voltage levels indicated
by Figure 9-1 when A C specifications are mea-
sured Intel386 DX output delays are specified with
minimum and maximum limits measured as shown
The minimum Intel386 DX delay times are hold times
