Abstract :
Commercial CMOS analog/digital processes are considered for spaceborne applications. Total dose hardness of three processes is compared by the testing of analog multiplexers. Parts were irradiated at 18 and 1.8 rad(Si) per sec. The total dose results are then compared with the requirements for a low Earth and a geosynchronous orbital design. Shielding thicknesses for each of the orbital designs are suggested
