Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If it functions primarily as a memory IC
Memory integrated circuits like amplifiers with memory are under 8542.32, separate from filter-specific ICs.
If for use in complete communication machines
ICs designed solely for machines of 8517 may shift to that heading if not general-purpose.
If imported as hybrid or multi-chip modules
Parts of ICs like hybrid assemblies fall under 8542.90 rather than monolithic active filters.
