The 40-682 Very High Density Versatile Multiplexer module features a wide range of selectable switching configurations. The 40-682 is especially useful where a high density MUX array is required that can adapt to different test configurations for different test targets, or where a test system may have to be reconfigured in the future. The 40-682 uses high performance solid state switching to ensure a service life of greater than 10 years and fast operation.
