DG186AP/883B

Analog Switches, Multiplexers, Demultiplexers Overview

The DG186AP/883B is a high-reliability single-ended multiplexer manufactured by Harris Corporation, designed for demanding environments. It features eight channels and operates within a temperature range of -55°C to +125°C. The device utilizes a ceramic LCC-20 package with glass-sealed construction to ensure durability. Key electrical specifications include a maximum on-resistance of 1500 Ω and an off-isolation of 68 dB. It supports nominal supply voltages of ±15 V and functions as a CMOS analog switch suitable for precision signal routing applications.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific manufacturer source, as original Harris assets are often managed by Rochester Electronics or similar distributors specializing in legacy components. Confirm that the MIL-STD-883 Class B screening status is explicitly documented in the current datasheet or certificate of compliance before finalizing procurement requirements.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a robust, hermetically sealed analog switch is required for extreme temperature conditions. Ensure the system design accommodates the 1500 Ω on-resistance and ±15 V supply voltage limits. Verify that the LCC-20 surface mount package aligns with the PCB layout constraints and thermal management strategy.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG186 series of analog multiplexers, characterized by its high-reliability ceramic packaging. The /883B suffix indicates compliance with MIL-STD-883 testing standards, distinguishing it from commercial variants. It serves as a specialized solution for applications where standard plastic-packaged ICs would fail due to environmental stressors.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Check for direct equivalents such as the DG186AP/883 or other MIL-spec multiplexers from manufacturers like Analog Devices or Texas Instruments. Ensure pin compatibility and electrical parameters match exactly, particularly the on-resistance and isolation levels.
