HI1-0548/883 Renesas

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