Several electronic device technologies (MOS, CMOS, GaAs) have been investigated for their suitability in an analogue signal multiplexer operating throughout the temperature range 4 K less than T less than 77 K. Constraints on leakage currents, channel resistance and radiation hardness led to the selection of GaAs as the candidate technology. Selected test results are presented and some problem areas identified.
