Abstract
A total dose radiation-resistant, high voltage CMOS process has been used to build both eight-and sixteen-channel analog multiplexers. The circuits are hardened versions of the Harris 508A and 1840 dielectrically isolated multiplexers, and meet all specifications of their non-hardened equivalents after total dose exposures of 100k and 200k rad(Si), respectively. The process, which yields circuits functional to a dose level of a megarad, is described. Circuit performance as a function of total dose is presented.
