Vishay Intertechnology recently expanded its family of MIL-PRF (military-performance-specification)-38535-screened analog switches and multiplexers with the release of the high-reliability, eight-channel, single-ended DG408 analog multiplexer. The device features a 44V maximum supply rating, on-resistance of 100Q, and charge injection of 20 pC. The DG408's Enable pin allows you to use multiple devices to increase the number of input signals in an application. The DG408 joins the previously released DG409 as a product that meets this new certification. Targeting use in high-speed data acquisi-tion, audio-signal routing, and battery-powered and remote instrumentation, the device connects one of eight inputs to a common output, which a 3-bit binary address determines. Vishay's additional high-reliabil-ity capabilities include Group A, Group B, Group C, and Group E testing. In addition, Vishay continues to offer source-controlled drawing capabilities to allow space- and avionic-level screening.
