DG405AK/883

Analog Switches, Multiplexers, Demultiplexers Overview

The DG405AK/883 is a high-performance, dual 4-channel CMOS analog multiplexer manufactured by Harris Corporation. It features dielectric isolation for latch-free operation and low leakage currents. The device operates over an extended temperature range of -55°C to +125°C and utilizes a 16-lead ceramic dual in-line package (CDIP). Designed for military and aerospace applications, it provides reliable signal routing with low on-resistance and fast switching speeds.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the manufacturer origin carefully, as Harris Corporation assets were acquired by Analog Devices. Confirm that the specific part number corresponds to original Harris production or authorized successor documentation. Ensure the CDIP-16 package matches the required form factor for the application.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when dual independent 4-channel switching is required in a single package. Consider the DG409 series if eight channels are needed instead. Verify voltage supply requirements align with the CMOS input thresholds and ensure the ceramic package fits the available board space.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the DG40x family of analog switches. These devices are widely used in precision measurement equipment. The /883 suffix indicates compliance with MIL-STD-883 standards, signifying suitability for rugged environments requiring high reliability and radiation hardness compared to commercial variants.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Check for availability from Analog Devices, which holds rights to the Harris linear product line. Verify pinout compatibility with direct replacements like the DG405CP or similar quad multiplexers if channel count allows.
