CD74HC4515EN

Overview

The CD74HC4515EN is a high-speed CMOS logic device manufactured by Texas Instruments, functioning as a 4-to-16-line decoder or demultiplexer. It operates within a supply voltage range of 2 V to 6 V and supports a wide operating temperature range from -55 °C to +125 °C. The component utilizes a 24-pin Plastic Dual In-Line Package (PDIP) for through-hole mounting. As part of the HC series, it provides standard decoding capabilities with inverted outputs suitable for general digital logic applications.

Feature Summary

• Functions as a single 4-to-16-line decoder or demultiplexer circuit
• Features inverted output polarity for signal compatibility
• Supports surface-mount and through-hole integration via PDIP packaging

Applications

• Digital address decoding in memory systems
• Data distribution in multiplexed display drivers
• Control signal routing in industrial automation interfaces

Procurement Notes

Verify the specific manufacturer origin, as this part number has been produced by multiple vendors including Renesas and Harris. Confirm that the PDIP package matches the required board layout. Ensure the HCT or HC logic family designation aligns with the system's voltage levels, as specifications vary between manufacturers despite the shared model number.

Selection Notes

Select this component when a through-hole 4-to-16 decoder is required for legacy PCB designs. Verify that the input logic thresholds match the driving source, particularly if mixing HC and HCT families. Consider the 24-pin DIP footprint constraints during mechanical design. Check for RoHS compliance status depending on the specific production batch and vendor.

Part Context

This device belongs to the Texas Instruments 74HC logic family, designed for high-speed CMOS operations. It serves as a functional equivalent to other industry-standard 4-to-16 decoders. The 'E' suffix typically denotes a specific environmental or packaging variant within the manufacturer's catalog structure.

FAQ

What is the output polarity of the CD74HC4515EN?

The outputs are inverted, meaning the selected line goes low while others remain high.

Does the CD74HC4515EN support bidirectional data flow?

No, it functions strictly as a decoder or demultiplexer with unidirectional data flow from inputs to outputs.
