IH5108CPE

Analog Switches, Multiplexers, Demultiplexers Overview

The IH5108CPE is a high-speed analog switch manufactured by Harris Corporation, now part of Analog Devices. It features eight independent SPST (Single-Pole Single-Throw) channels within a single package, designed for applications requiring multiple signal routing paths. The device utilizes CMOS technology to achieve low on-resistance and fast switching speeds. It operates with a wide supply voltage range, supporting both single and dual power supplies. The component is housed in a standard 16-pin Plastic Dual In-line Package (PDIP), facilitating through-hole mounting on printed circuit boards. Its architecture allows for efficient multiplexing and demultiplexing of analog signals in data acquisition systems.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the manufacturer lineage carefully, as Harris Corporation's semiconductor assets were acquired by Intersil and subsequently by Renesas and Analog Devices. Ensure the specific ordering suffix matches the required package type and temperature grade. Confirm RoHS compliance status, as older Harris-branded parts may not meet current environmental standards. Request detailed datasheets from authorized distributors to verify pinout compatibility and electrical characteristics against original specifications.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a design requires eight isolated analog switches in a compact footprint. Compare on-resistance and leakage current specifications against alternative CMOS switches if signal integrity is critical. Consider the PDIP package constraints regarding thermal dissipation and board space. Verify that the operating voltage range aligns with the system's power rails. Evaluate switching speed requirements to ensure the device meets the bandwidth needs of the application.

Analog Switches, Multiplexers, Demultiplexers Part Context

The IH5108 series belongs to the family of high-speed analog switches developed by Harris Semiconductor. These components were widely used in the 1990s and early 2000s for various electronic systems before being integrated into larger semiconductor portfolios following corporate acquisitions. The CPE suffix denotes the plastic DIP package variant. Understanding this historical context is important for sourcing replacement parts and verifying technical documentation availability from current manufacturers.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Potential substitutes include the ADG508F or MAX408 from Analog Devices/Maxim, which offer similar functionality and pinouts. Verify electrical parameters such as Ron and switching times to ensure compatibility. Check for package equivalence and lead configuration. Consult current manufacturer cross-reference guides for updated part numbers reflecting modern manufacturing processes.
