"Circuit Selects Single Or Multiple Lines," Bob Mostafapour, EDN September 17, 1987

A simple circuit to emulate an interlocking selector with momentary pushbutton switches. The left-hand side of the circuit, which is optional, allows simultaneous selection of multiple outputs. If IC1 is not used the 1 uF caps are not needed and the pull-down resistors should be grounded.
