  I've used Siliconix DG-series parts for 20 years.  In my opinion *the* 
analog switches/muxen of choice.  DG308A is quad SPST, DG309A is quad SPST 
with inverse switch logic, DG508A 8:1 mux, DG509A dual 4:1 mux (these have 
TTL-compatible control inputs even at +/-15V supply), to name just a few.

  Siliconix is now Vishay-Siliconix, and the 508/509 are superceded by the 
408/409.  Analog Devices also 2nd-sources many of the parts.  There are 
all sorts of DG parts in the catalog.
