Procurement Notes

Verify the manufacturer designation on the component marking, as Texas Instruments acquired Harris Semiconductor's logic business. Confirm the specific package variant matches the required PCB footprint. Ensure the part number suffix corresponds to the intended tape-and-reel or tube packaging configuration for assembly compatibility.

Selection Notes

Select this component when a single-channel 4-to-16 decoding function is required within the HC logic family. Consider the 24-pin DIP package for through-hole prototyping or legacy board designs. Verify that the input voltage levels are compatible with the system logic standards before integration into the design.

Part Context

This component belongs to the CD74HC451x series of decoders and demultiplexers. It shares functional similarities with other devices in the family but is distinguished by its specific output count and Harris Corporation manufacturing origin prior to industry consolidation.
