SWITCHING CHARACTERISTICS
The switching characteristics given consist of output
delays, input setup requirements, and input hold re-
quirements. All switching characteristics are relative to
the CLK2 rising edge crossing the 2.0-V level.
Switching characteristic measurement is defined in
Figure 2. Inputs must be driven to the voltage levels in-
dicated by Figure 2 when switching characteristics are
measured. Output delays are specified with minimum
and maximum limits measured, as shown. The mini-
mum delay times are hold times provided to external
circuitry. Input setup and hold times are specified as
minimums, defining the smallest acceptable sampling
window. Within the sampling window, a synchronous
input signal must be stable for correct operation.
Outputs ADS, W/R, D/C, M/IO, LOCK, BHE, BLE,
A23–A1, HLDA, and SMIADS* only change at the be-
ginning of phase one. D15–D0 and SMI* write cycles
only change at the beginning of phase two. The
READY, HOLD, BUSY, ERROR, PEREQ, FLT, D15–
D0, IIBEN*, and SMIRDY* read cycles inputs are sam-
pled at the beginning of phase one. The NA, INTR,
NMI, and SMI* inputs are sampled at the beginning of
phase two.
