DATASHEET HI-548/883, HI-549/883 FN8256 Rev.0.00 Single 8/Differential 4-Channel CMOS Analog Multiplexers with April 9, 2012 Active Overvoltage Protection The HI-548/883 and HI-549/883 are analog multiplexers with Features active overvoltage protection and guaranteed r matching. ON This Circuit is Processed in Accordance to MIL-STD-883 and Analog input levels may greatly exceed either power supply is Fully Conformant Under the Provisions of Paragraph 1.2.1. without damaging the device or disturbing the signal path of other channels. Active protection circuitry assures that signal No Channel Interaction During Overvoltage fidelity is maintained even under fault conditions that would Guaranteed r Matching ON destroy other multiplexers. 44V Maximum Power Supply Analog inputs can withstand constant 70V levels with 15V P-P Break-Before-Make Switching supplies. Digital inputs will also sustain continuous faults up to 4V greater than either supply. In addition, signal sources are Analog Signal Range . 15V protected from short circuiting should multiplexer supply loss Access Time (Max) . 1.0s occur. Each input presents 1k of resistance under this Power Dissipation (Max) . 45mW condition. These features make the HI-548/883 and HI-549/883 ideal for use in systems where the analog inputs Applications originate from external equipment or separately powered circuitry. Both devices are fabricated with 44V Dielectrically Data Acquisition Systems Isolated CMOS technology. The HI-548/883 is an 8-channel Control Systems device, and the HI-549/883 is a 4-channel differential version. Telemetry If input overvoltage protection is not needed, the HI-508/883 and HI-509/883 multiplexers are recommended. For further information see Application Note AN520.
