CD74HC4515M

Overview

The CD74HC4515M is a high-speed CMOS logic decoder/demultiplexer manufactured by Texas Instruments. It features one circuit with four inputs and sixteen outputs, housed in a 24-pin SOIC package. The device operates within a supply voltage range of 2V to 6V and supports an operating temperature range from -55°C to +125°C. It provides symmetrical output impedance and low power dissipation characteristics typical of the HC series.

Feature Summary

• Provides 4-to-16 line decoding functionality with inverted outputs
• Features high noise immunity and symmetrical output drive capability
• Operates across a wide voltage range for flexible system integration

Applications

• Data routing and signal distribution systems
• Memory address decoding circuits
• Industrial control logic interfaces

Procurement Notes

Verify the specific suffix 'M' indicates the standard SOIC-24 plastic package configuration. Confirm RoHS compliance status as documentation may vary by manufacturing batch. Ensure the ordering part number matches the exact pinout and electrical specifications required for the target application design.

Selection Notes

Select this component when a single 4-to-16 demultiplexer with inverted outputs is required. Compare against the CD74HC4514 if non-inverted outputs are needed instead. Consider the HCT variant if direct compatibility with TTL logic levels is necessary rather than standard CMOS levels.

Part Context

This device belongs to the Texas Instruments 74HC family of high-speed CMOS logic devices. It serves as a functional equivalent to other industry-standard 4-to-16 decoders. The component is designed for general-purpose digital applications requiring reliable signal decoding and distribution capabilities.

FAQ

What is the output polarity of the CD74HC4515M?

The CD74HC4515M provides inverted outputs, distinguishing it from the non-inverting CD74HC4514.

Does the CD74HC4515M include input latches?

No, the CD74HC4515M does not feature input latches; it functions strictly as a decoder/demultiplexer.
