1) The input and output parameter values in this table are directly related to ambient temperature and DC supply

affect these values and must be evaluated extra.

2) Static supply current IDDS is exclusive of input/output drive requirements and is measured at maximum VDD

with the clocks stopped and all inputs tied to VDD or VSS, configured to draw minimum current.

3) Operating current is exclusive of input/output drive requirements and is measured at maximum VDD and maxi-

mum clock frequency 20 MHz.
