Abstract
Abstract An integrated circuit socket is provided with an insulating member and a plurality of conductive socket pins extending from the insulating member. These socket pins are adapted to be electrically connected to the pins of an integrated circuit. A plurality of impedance elements are mechanically supported by the insulating member. Switches are provided for selectively connecting each of the impedance elements to, or isolating each of the impedance elements from, at least one of the socket pins, thereby providing the flexibility to terminate any combination of pins on the integrated circuit.
