CD74HC4514EN

Overview

The CD74HC4514EN is a high-speed CMOS decoder/demultiplexer from the Texas Instruments 74HC series. It features one circuit with four inputs and sixteen outputs, housed in a 24-pin PDIP package. The device operates on a single power supply ranging from 2 V to 6 V. Key electrical parameters include a propagation delay of 69 ns at nominal supply voltage and a load capacitance of 50 pF. It supports surface mount and through-hole installation styles, functioning within an operating temperature range of -40 °C to +85 °C.

Feature Summary

• Provides 4-to-16 line decoding and demultiplexing functionality within a single integrated circuit.
• Utilizes high-speed CMOS technology for efficient signal processing.
• Features active output drivers capable of sinking and sourcing current.

Applications

• Data routing and distribution systems
• Address decoding in memory architectures
• Control logic for peripheral selection

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.

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.

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. The device is part of the broader 74HC series, known for wide operating voltage ranges and compatibility with standard CMOS logic levels.

Replacement Considerations

CD74HC4514M96: Surface-mount alternative with identical logical function but different package type (SOIC-24 vs PDIP-24).
