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 channelto- channel interference.
The DG458 and DG459 are improved pin-compatible replacements for HI-508A/509A and MAX358/359 multiplexers.
