AC ELECTRICAL SPECIFICATION DEFINITIONS
The AC specifications presented consist of output delays, input setup and hold times and signal skew times. All
signals are specified relative to an appropriate edge of the clock and possibly to one or more other signals.
The measurement of the AC specifications is defined by the waveforms shown in Figure 6. To test the parameters
guaranteed by Motorola, inputs must be driven to the voltage levels specified in the figure. Outputs are specified
with minimum and/or maximum limits, as appropriate, and are measured as shown. Inputs are specified with
minimum setup and hold times, and are measured as shown. Finally, the measurement for signal-to-signal
specifications are shown.
Note that the testing levels used to verify conformance to the AC specifications does not affect the guaranteed
DC operation of the device as specified in the DC electrical characteristics.
