DG408AK/883B

Analog Switches, Multiplexers, Demultiplexers Overview

The DG408AK/883B is a high-reliability 8:1 CMOS analog multiplexer switch manufactured by Analog Devices under the Maxim Integrated brand. Designed for military and aerospace applications, it features a ceramic dual in-line package (CDIP-16) with hermetic sealing. The device operates on single or dual power supplies ranging from 4.5V to 30V. Key electrical specifications include a maximum on-resistance of 100 Ohms, a maximum propagation delay of 250 ns, and a maximum supply current of 500 uA. It supports an operating temperature range from -55°C to +125°C and dissipates up to 800 mW.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify authenticity through authorized distributors or direct manufacturer channels due to restricted availability. Confirm that the specific suffix denotes military-grade qualification and hermetic packaging. Check for obsolescence status as this component may be subject to limited production runs or special factory orders rather than standard commercial inventory.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when hermetic sealing and wide temperature tolerance are mandatory requirements. Ensure the design accommodates the CDIP-16 through-hole footprint. Verify that the 100 Ohm on-resistance meets the signal integrity requirements of the application compared to lower-resistance alternatives.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG408 series of analog switches. The AK/883B suffix typically indicates a specific military or space-grade variant with enhanced reliability standards compared to commercial versions like the DG408DJ+. It shares functional compatibility with other members of the DG408 family but differs in packaging and environmental ratings.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct replacements must match the CDIP-16 hermetic package and 8:1 configuration. Commercial equivalents such as the DG408DJ+ lack hermetic sealing and different temperature ranges. Verify pinout compatibility before substituting with other 8-channel multiplexers.
