IH5014CDD

Analog Switches, Multiplexers, Demultiplexers Overview

The IH5014CDD is a CMOS analog switch manufactured by Harris Corporation, belonging to the IH5009 series. It features four independent channels configured as single-pole double-throw (SPDT) switches within a 20-pin ceramic dual in-line package (CDIP). The device supports dual power supplies ranging from ±4.5V to ±18V and operates across a temperature range of -55°C to +125°C. Key electrical characteristics include an on-resistance between 5Ω and 50Ω, off-isolation exceeding 60dB, and leakage currents below 500pA at 70°C. Designed for industrial and military applications, it interfaces directly with TTL logic without external drivers.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to legacy status. Confirm specific suffix designations match required pinout and thermal specifications. Request detailed lot traceability documentation for aerospace or defense procurement compliance. Validate that the ceramic package variant meets vibration and shock requirements for the intended deployment environment.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when high channel density and direct TTL compatibility are required in harsh environments. Compare against plastic variants if cost reduction is prioritized over extreme temperature stability. Ensure supply chain availability aligns with long-term production cycles given the component's age. Evaluate alternative quad SPDT devices if lower on-resistance is critical for high-frequency applications.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the Harris IH5009 series of analog switches, designed to provide versatile signal gating solutions. Harris Corporation, later acquired by Intersil and subsequently Renesas Electronics, produced this line for demanding industrial and military sectors. The CDIP package indicates a hermetically sealed construction typical for radiation-hardened or high-reliability applications in avionics and defense systems.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Publicly confirmed substitute part numbers are not available in verified sources. Consider equivalent quad SPDT CMOS analog switches from current manufacturers offering military-grade ceramic packages. Verify pin compatibility and electrical parameters before substitution to ensure system integrity.
