Parametera

a. Rise and fall times are specified in terms of the edge rate measured in V/ns. This slew rate must be met across the

minimum peak-to-peak portion of the clock waveform as shown.

b. The minimum RST# slew rate applies only to the rising (de-assertion) edge of the reset signal and ensures that system

noise cannot render a monotonic signal to appear bouncing in the switching range.
