DG185BP

Analog Switches, Multiplexers, Demultiplexers Overview

The DG185BP is a dual double-pole single-throw (DPST) analog switch manufactured by Harris Corporation, now part of L3Harris Technologies. It features a ceramic flat package with 14 pins and operates within a temperature range of -55 °C to 125 °C. The device provides separate outputs for accurate switching of video and audio signals. It is designed for applications requiring constant on-resistance over the entire analog range and offers low leakage, low crosstalk, and break-before-make switching characteristics.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify manufacturer lineage as Harris Corporation assets are managed by L3Harris. Confirm lead time and availability directly with authorized distributors or the manufacturer. Ensure compliance with specific military qualification requirements if applicable to the end-use environment.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when radiation hardness and high reliability are required for analog signal switching. Compare on-resistance stability and leakage current specifications against alternative DPST switches. Verify package compatibility and thermal management needs for the operating temperature range.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the DG183/184/185 series of precision analog switches. These devices are distinguished by their constant on-resistance and suitability for demanding environments. The series is widely recognized in aerospace and defense sectors for robust performance under extreme conditions.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct substitutes include DG183 and DG184 variants from the same family. Verify pinout compatibility and electrical parameters before substitution. Alternative manufacturers may offer similar DPST switches but require validation of radiation tolerance and package dimensions.
