The DG458 and DG459 are 8-channel single-ended and
4-channel differential analog multiplexers, respectively,
incorporating fault protection. A series n-p-n MOSFET
structure provides device and signal-source protection in the
event of power loss or overvoltages. Under fault conditions the
multiplexer input (or output) appears as an open circuit and
only a few nanoamperes of leakage current will flow. This
protects not only the multiplexer and the circuitry following it,
but also protects the sensors or signal sources which drive the
multiplexer.
