ABSTRACT:
A multi-stage analog bi-directional selector which has a low input impedance and cost. The multi-stage analog bi-directional selector includes a plurality of analog switches including first and second bi-polar transistors coupled together at first and second connection points, a primary channel coupled to the first connection points, a plurality of data channels coupled to the second connection points, and an address circuit which causes a single one of the analog switches to form a bi-directional analog data connection between a corresponding single one of the data channels and the primary channel.
