74HCT4514N,652

Signal Switches, Multiplexers, Decoders Overview

The 74HCT4514N,652 is a 4-to-16 line decoder and demultiplexer manufactured by Nexperia (formerly NXP Standard Products). It belongs to the HCT logic family, utilizing CMOS technology. The device features input latches for address data storage. It operates within a supply voltage range of 4.5 V to 5.5 V. The component is housed in a PDIP-14 package designed for through-hole mounting. It supports an operating temperature range from -40 °C to +125 °C. Propagation delay is specified at 50 ns.

Signal Switches, Multiplexers, Decoders Feature Summary

• Integrates four input latches to store address data independently of the decoding process.
• Functions as a 4-to-16 line decoder or demultiplexer with active-high outputs.
• Compatible with standard TTL output levels due to HCT CMOS construction.

Signal Switches, Multiplexers, Decoders Applications

• Address decoding in memory systems
• Demultiplexing data streams in digital circuits
• Control signal distribution in industrial automation

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify current availability status as this part number may be subject to discontinuation or lifecycle changes. Confirm that the PDIP-14 through-hole package meets mechanical constraints. Ensure the HCT logic level compatibility aligns with system voltage requirements before procurement.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when a 4-to-16 decoding function with input latching is required in a through-hole design. The HCT series ensures compatibility with 5 V TTL logic interfaces. Verify that the 50 ns propagation delay satisfies timing constraints for the specific application frequency.

Signal Switches, Multiplexers, Decoders Part Context

This component is part of the 74HCT4514 family of decoders and demultiplexers. It shares functional similarities with other 4-to-16 decoders but is distinguished by its integrated input latches and HCT logic compatibility. The manufacturer transitioned from NXP to Nexperia for standard products, affecting branding but not electrical specifications.
