HI1-546-5 DIP

The HI-546, HI-547, HI-548 and HI-549 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.
