A receiver circuit (16) is programmable to operate with different logic family driver circuits (10). The receiver circuit has two external configuration pins (22,) 24) that are configured to provide the necessary termination for the type of logic family driver circuit used. To terminate the receiver circuit (16) for an ECL application will require first and second configuration pins (22,24) are connected to VCC—2 volts. To terminate the receiver circuit (16) for a CML application will require the first configuration pin (22) and the second configuration pin (24) are connected to VCC. LVDS termination for the receiver circuit (16) requires the first configuration pin (22) and the second configuration pin (24) are connected together. The configuration pins are external to a semiconductor package (14) housing the receiver circuit.
