DG401AK/883

Analog Switches, Multiplexers, Demultiplexers Overview

The DG401AK/883 is a high-reliability, dual single-pole double-throw (SPDT) analog switch manufactured by Harris Corporation. It utilizes CMOS technology and is housed in a CDIP-16 ceramic package designed for military specifications. The device supports dual power supplies ranging from ±5V to ±20V, enabling an analog signal range of ±15V. Key electrical parameters include a maximum on-resistance of 100 ohms, an on-resistance matching specification of 15 ohms, and a typical leakage current of 1 nA at +25°C. The component operates within a temperature range of -55°C to +125°C and features break-before-make switching action.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Dual SPDT configuration providing two independent analog signal paths
• Frit-sealed ceramic DIP package ensuring environmental stability
• Break-before-make switching action prevents signal shorting during transitions

Analog Switches, Multiplexers, Demultiplexers Applications

• Military data acquisition systems requiring high reliability
• Precision automatic test equipment
• Harsh environment communication systems

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the authenticity of the DG401AK/883 through authorized distributors or certified surplus dealers. Request full traceability documentation, including lot codes and material certifications, to confirm compliance with MIL-STD-883 standards. Ensure the ceramic package integrity is intact upon receipt to maintain hermetic sealing properties essential for this component's operational lifespan.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the DG401AK/883 when dual-channel isolation is required in space-constrained military applications. Compare its 100-ohm on-resistance against lower-resistance alternatives if signal attenuation is critical. Confirm that the ±15V signal range aligns with system voltage requirements. Verify that the CDIP-16 footprint matches the target PCB layout constraints.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the Harris DG40x series of precision analog switches. The 'AK' suffix typically denotes a specific thermal or mechanical variant within the military grade lineup. The '/883' designation indicates adherence to MIL-STD-883 testing standards. This series is distinct from the DG409 multiplexer family, offering dedicated SPDT functionality rather than multi-channel switching.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct replacements may include the DG401AJ/883B or equivalent parts from Analog Devices or Vishay. Verify pin compatibility and ensure the substitute meets the same MIL-STD-883 qualification levels. Cross-reference on-resistance and leakage current specifications to guarantee functional equivalence in sensitive analog circuits.
