HI1-0518-2 is listed in the Analog Switches, Multiplexers, Demultiplexers range at ChipApex. The manufacturer field lists Harris Corporation. Its product description is IC SW 4PST-NOX2 750OHM 18CERDIP. Review the specifications below when checking this part for your BOM.
The HI1-0518-2 is a dual-circuit analog switch manufactured by Harris Corporation, housed in an 18-pin CERDIP package. It functions as a 4:1 multiplexer or demultiplexer with a maximum on-state resistance of 750 Ohms. The device operates on a single positive supply voltage of 15V. Designed for high-performance signal routing, it provides two independent switching circuits within a single integrated circuit form factor suitable for military and aerospace applications.
Verify the specific manufacturer source when procuring this component, as Harris Corporation assets have been acquired by other entities such as L3Harris. Ensure that the received unit matches the original specifications and physical characteristics of the HI1-0518-2 designation. Cross-reference datasheets from current authorized distributors to confirm active status and technical compliance before integration into designs.
Select this component when a dual-channel analog switch with low on-resistance is required for critical signal paths. The 18-pin CERDIP package offers superior thermal and mechanical stability compared to plastic packages. Consider the 750 Ohm on-state resistance limit when designing for minimal signal attenuation. This part is suitable for applications demanding high reliability and radiation tolerance inherent to ceramic construction.
This analog switch belongs to the family of high-performance interface components produced by Harris Semiconductor. These devices were widely utilized in defense and industrial sectors where reliability under extreme conditions was paramount. The transition of Harris's semiconductor division has led to various availability channels, making verification of authenticity and specification consistency essential for engineers maintaining legacy systems or designing new ruggedized hardware.
