An N-wire interleaved differential multiplexer. The N-wire interleaved differential multiplexer may be formed by interleaving the channels and corresponding switches of N one-wire multiplexers. Each of the switches of the interleaved differential multiplexer may be controlled independent from the other switches to provide a signal path between a DUT stack and a measurement device. To test a first DUT, two switches of the interleaved multiplexer are closed to connect the terminals of the first DUT to the measurement device. To switch from testing the first DUT to testing a subsequent DUT, one of the previously activated switches is opened, one is kept closed, and a different switch is closed. The testing process may "walk" up or down the switch channels of the interleaved multiplexer one switch at a time to test each of the DUTs of the DUT stack.
