The BJT configuration for SPDT, single pole double throw

Draw the complete circuit (minus the SPDT solution) as to how its used ?

You looking to implement a 2 in 1 out logic level mux, or an analog mux ?

What is the physical layer attributes of your SPDT switch ?


Regards, Dana.

All analog and/or logic signals must be defined a priori asking this question.
Also: input, output or bidirectional or just complementary?
