DG300AAK/883

Analog Switches, Multiplexers, Demultiplexers Overview

The DG300AAK/883 is a dual single-pole single-throw (SPST) CMOS analog switch manufactured by Vishay Siliconix. It operates within a full rail-to-rail analog signal range of ±15 V and features a maximum on-resistance of 50 Ω at room temperature, extending to 75 Ω across the full operating range. The device supports single or dual supply configurations with a maximum positive supply voltage of 44 V. Key dynamic characteristics include a maximum turn-on time of 300 ns and a maximum turn-off time of 250 ns. It is housed in a 14-pin ceramic dual-in-line package (CDIP-14) designed for military specifications.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Monolithic CMOS construction provides latch-up protection and low power dissipation suitable for battery-powered systems.
• Designed for break-before-make switching action to prevent signal shorting during state transitions.
• CMOS and quasi-TTL compatible logic inputs allow direct interfacing with standard digital control circuits.

Analog Switches, Multiplexers, Demultiplexers Applications

• Low level switching circuits requiring minimal signal distortion
• Programmable gain amplifiers with digitally selectable inputs
• Portable and battery powered instrumentation systems

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify component authenticity through authorized distributors or official manufacturer channels. Confirm that the part number suffix /883 corresponds to the specific military-grade JM38510 qualification requirements. Ensure the CDIP-14 package matches the target PCB footprint and thermal management constraints before finalizing procurement orders.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a ruggedized, hermetically sealed dual SPST switch is required for harsh environments. Consider the 50 Ω on-resistance and 300 ns switching speed against system timing budgets. Verify that the ±15 V supply rails align with the application's analog signal range and power availability constraints.

Analog Switches, Multiplexers, Demultiplexers Part Context

This device belongs to the DG300A_MIL series of monolithic CMOS switches produced by Vishay Siliconix. It is specifically qualified under the JM38510 military specification standards. The product line includes complementary variants such as the DG301A_MIL (SPDT) and DG302A_MIL (DPST), offering different channel configurations within the same robust package family.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The datasheet explicitly states that the DG300B Series serves as pin-for-pin replacements for non-hermetic versions. For the /883 military variant, verify if equivalent MIL-spec alternatives are available from current production lines, as the original manufacturing may be obsolete.
