IH5020CDE

Analog Switches, Multiplexers, Demultiplexers Overview

The IH5020CDE is a CMOS analog switch manufactured by Harris Corporation, housed in a CDIP16 package. It functions as a dual single-pole double-throw (SPDT) switch with one channel per switch element. The device supports an external data bus width of 8 bits and operates within a maximum clock frequency of 16 MHz. It utilizes NRZ data encoding/decoding methods and is compatible with the 80C86 and 80C88 bus architectures. The component features low power consumption modes and is designed for serial I/O control applications.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the manufacturer origin carefully, as Harris Corporation assets were acquired by Renesas Electronics. Confirm whether the specific unit is an original Harris production or a Renesas continuation to ensure supply chain consistency. Check RoHS compliance status as older Harris components may not meet current environmental standards. Validate the package integrity for the CDIP16 form factor upon receipt.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a dual SPDT analog switching solution is required for CMOS logic levels. Ensure the system voltage requirements align with the device's operational range. Consider the CDIP16 package constraints if surface mount alternatives are preferred. Verify that the 16 MHz maximum clock frequency meets the timing requirements of the target application interface.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the Harris IH50xx series of analog switches. The series includes variants like the IH5043CDE and IH5050CWE-T, which share similar CMOS technologies but differ in package types and specific functional configurations. The IH5020CDE specifically addresses dual-channel switching needs in legacy industrial and embedded systems.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Renesas Electronics continues the IH50xx line following the acquisition of Harris Semiconductor assets. Verify part number continuity with Renesas documentation. Cross-reference with other dual SPDT CMOS switches if pin compatibility is critical.
