10.0 AC Parameters
The AC timing diagrams presented in this section assume that the outputs of the ARM60 have been loaded
with the capacitive loads shown in the `Test Load' column of Table 29: AC Test Loads . These loads have been
chosen as typical of the type of system in which ARM60 might be employed.
The output drivers of the ARM60 are CMOS inverters which exhibit a propagation delay that increases
linearly with the increase in load capacitance. An `Output derating' figure is given for each output driver,
showing the approximate rate of increase of output time with increasing load capacitance.
