ELECTRICAL CHARACTERISTICS
AC ELECTRICAL SPECIFICATION DEFINITIONS
The AC specications presented consist of output delays, input setup and hold times and signal skew times. All
signals are specied relative to an appropriate edge of the clock and possibly to one or more other signals.
The measurement of the AC specications is dened by the waveforms shown in Figure 6. To test the parameters
guaranteed by Motorola, inputs must be driven to the voltage levels specied in the gure. Outputs are specied
with minimum and/or maximum limits, as appropriate, and are measured as shown. Inputs are specied with
minimum setup and hold times, and are measured as shown. Finally, the measurement for signal-to-signal
specications are shown.
Note that the testing levels used to verify conformance to the AC specications does not affect the guaranteed
DC operation of the device as specied in the DC electrical characteristics.
a. Not including internal pull-up or pull-down.
b. Currents listed are with no loading.
c. Capacitance is periodically sampled rather than 100% tested.
