Description
Fault-protected Single 8-ch/differential 4-ch Analog Multiplexers
Manufacturer
Vishay
Datasheet
DESCRIPTION
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
multiplexers.
