MC68EC020 DC Electrical Characteristics
NOTE: Capacitance is periodically sampled rather than 100% tested.
10.3 AC ELECTRICAL CHARACTERISTICS
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
10-1. To test the parameters guaranteed by Motorola, inputs must be driven to the voltage
levels specified in Figure 10-1. Outputs are specified with minimum and/or maximum
limits, as appropriate, and are measured as shown in Figure 10-1. Inputs are specified
with minimum setup and hold times, and are measured as shown. Finally, the
measurement for signal-to-signal specifications is also shown.
Note that the testing levels used to verify conformance to the AC specifications do not
affect the guaranteed DC operation of the device as specified in the DC electrical
specifications. The 20 MHz and 33.33 MHz specifications do not apply to the
MC68EC020.
