Abstract
A test driver transmitter drives a test signal through a resistive termination circuit to a first pin to test components on a board during a boundary scan test operation. A test receiver receives the test signal through a second pin and a pass gate coupled to the second pin during the boundary scan test operation. A test signal is transmitted to the test receiver during loopback operation through a loopback circuit.
