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.
The DG458 and DG459 can withstand continuous overvoltage
inputs up to 35 V. All digital inputs have TTL compatible logic
thresholds. Break-before-make operation prevents channel-
to-channel interference.
The DG458 and DG459 are improved pin-compatible
replacements for HI-508A/509A and MAX358/359
multiplexers.
