    Single 8/Differential 4-Channel CMOS Analog
    Multiplexers with Active Overvoltage Protection
    HI-548/883, HI-549/883 Features The HI-548/883 and HI-549/883 are analog multiplexers with
    active overvoltage protection and guaranteed rON matching.
    Analog input levels may greatly exceed either power supply
    without damaging the device or disturbing the signal path of
    other channels. Active protection circuitry assures that signal
    fidelity is maintained even under fault conditions that would
    destroy other multiplexers. This Circuit is Processed in Accordance to MIL-STD-883 and
    is Fully Conformant Under the Provisions of Paragraph 1.2.1. Analog inputs can withstand constant 70VP-P levels with В±15V
    supplies. Digital inputs will also sustain continuous faults up to
    4V greater than either supply. In addition, signal sources are
    protected from short circuiting should multiplexer supply loss
    occur. Each input presents 1kΩ of resistance under this
    condition. These features make the HI-548/883 and
    HI-549/883 ideal for use in systems where the analog inputs
    originate from external equipment or separately powered
    circuitry. Both devices are fabricated with 44V Dielectrically
    Isolated CMOS technology. The HI-548/883 is an 8-channel
    device, and the HI-549/883 is a 4-channel differential version.
    If input overvoltage protection is not needed, the HI-508/883
    and HI-509/883 multiplexers are recommended. For further
