General Description :
What are the Quiescent Supply currents for the various 9500 parts?
9500 devices are sense-amp based; therefore, the value of the sense amp has direct correlation to the power consumption, so power consumption varies greatly with the pattern programmed into the device. This is not the case with pure CMOS devices such as the CoolRunner families (XPLA3 and CRII). With pure CMOS devices, the quiescent power is predictable and not affected (to a significant degree) by the pattern programmed into it.
