I would like to find a simple circuit for a TTL controlled analog switch. When the logic input is in one state, I'd like the switch to pass a +/- 10v analog signal. When the logic input is in the other state, I'd like the analog output to be ground. I'm sure this is simple, but a solution has so far eluded my mechanical engineer's brain. Any help or pointers would be appreciated. -Dave

They are CMOS but they should work with TTL signals as well. I am not dure of the specs now but your analog signal must be high-impedance; I doubt that the chips will pass thru more than 10mA but check the data sheet to make sure. Reha
