16-Channel, 8-Channel, Differential 8-Channel and Differential 4-Channel, CMOS Analog MUXs with Active Overvoltage Protection

The HI-506A, HI-507A, HI-508A and HI-509A are analog multiplexers with active overvoltage protection. 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. Analog inputs can withstand constant 70VP-Plevels with ±15V supplies.
