HI7131CM44S2324

Encoders, Decoders, Converters Overview

The HI7131CM44S2324 is a monolithic CMOS analog switch manufactured by Harris Corporation. It features four independent single-pole double-throw (SPDT) switches designed for high-performance signal routing applications. The device operates with a supply voltage range of ±5V to ±18V, providing low on-resistance and excellent channel-to-channel isolation. Key electrical characteristics include a typical on-resistance of 10 ohms and an off-isolation of -60dB at 1MHz. The component utilizes a standard 16-pin DIP package, suitable for through-hole mounting in various electronic circuits requiring precise analog signal control.

Encoders, Decoders, Converters Procurement Notes

Verify the specific suffix 'S2324' against official Harris or subsequent owner datasheets to confirm pinout compatibility and package variant. Ensure the component meets required operating temperature ranges for the intended environment. Cross-reference part numbers with current manufacturers holding rights to legacy Harris logic products to guarantee authenticity and traceability.

Encoders, Decoders, Converters Selection Notes

Select this component when designing circuits requiring multiple SPDT switches within a single package. Consider the ±5V to ±18V supply range compatibility with existing system rails. Evaluate the 10 ohm on-resistance against signal integrity requirements. Verify that the 16-pin DIP package fits the PCB layout constraints compared to surface-mount alternatives.

Encoders, Decoders, Converters Part Context

This component belongs to the family of CMOS analog switches produced by Harris Semiconductor before its acquisition by Intersil and later Renesas. These devices were widely used in professional audio and test equipment. The HI7131 represents a quad SPDT configuration, offering a compact solution for replacing discrete relay or transistor switching networks in analog signal paths.

Encoders, Decoders, Converters Replacement Considerations

Check for equivalents from Intersil or Renesas under updated part numbering schemes. Verify functional compatibility with other quad SPDT CMOS switches such as the CD4066 series, noting differences in on-resistance and leakage current specifications.
