Single 16/Differential 8-Channel CMOS Analog
Multiplexers with Active Overvoltage Protection
HI-546/883, HI-547/883 Features
The HI-546/883 and HI-547/883 are analog multiplexers with This circuit is processed in accordance to MIL-STD-883 and
active overvoltage protection and guaranteed r matching. is fully conformant under the provisions of Paragraph 1.2.1.
