Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific suffix 'EN' against the manufacturer's official datasheet to confirm the PDIP-24 package and commercial temperature grade (-40°C to +85°C). Ensure compatibility with existing PCB footprints designed for dual-in-line packages. Cross-reference RoHS compliance status with the latest environmental declarations provided by Texas Instruments prior to final procurement decisions.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when a 4-input to 16-output decoding function is required in a through-hole design. Compare the 69 ns propagation delay against system timing requirements. Consider the 74HC logic family voltage range (2V–6V) for interface compatibility. Evaluate the PDIP-24 package dimensions against available board space constraints compared to SOIC alternatives.

Signal Switches, Multiplexers, Decoders Part Context

This part belongs to the Texas Instruments 74HC4514 family of decoders and demultiplexers. It is a variant of the standard 74HC4514 logic gate, specifically packaged in a plastic dual-in-line format.
