Key Parameters

Substitute Part Grouping Explanation

Substitution of the 74HCT4515D,652 is determined by the following critical parameters:

• Functional Equivalence: Decoder/Demultiplexer type with 1 x 4:16 circuit configuration
• Package Compatibility: 24-SOIC surface mount package with identical pin pitch and dimensions
• Electrical Compatibility: Single supply voltage operation with overlapping supply voltage ranges
• Output Current Capability: Output drive current specifications must meet or exceed the original 4mA requirement
• Temperature Range: Operating temperature range must encompass the original -40°C ~ 125°C specification
• Compliance Standards: RoHS3 compliance and MSL rating consistency

The CD74HC4515M from Texas Instruments meets all substitution criteria as a functionally equivalent alternative.

Parameter Comparison

Engineering Selection Recommendations

The CD74HC4515M is a direct functional substitute for the 74HCT4515D,652. Both components share identical package geometry, circuit configuration, and compliance certifications. The substitute part provides enhanced output current capability (5.2mA versus 4mA) and an extended supply voltage range (2V ~ 6V versus 4.5V ~ 5.5V), offering improved operational flexibility. The extended lower temperature rating (-55°C versus -40°C) provides additional environmental margin. Both parts maintain ROHS3 compliance and MSL 1 rating, ensuring compatibility with standard manufacturing and storage protocols.

Frequently Asked Questions (FAQ)

Q: Can the CD74HC4515M be used as a direct replacement for the 74HCT4515D,652?

A: Yes. Both components feature identical 1 x 4:16 decoder/demultiplexer functionality, 24-SOIC package geometry, and pin configuration. The substitute part meets or exceeds all electrical specifications of the original component.

Q: What are the key differences between these parts?

A: The CD74HC4515M provides higher output current capability (5.2mA versus 4mA), a wider supply voltage range (2V ~ 6V versus 4.5V ~ 5.5V), and an extended lower operating temperature limit (-55°C versus -40°C). These differences represent improvements over the original specification.

Q: Are there any package or pinout considerations?

A: No. Both parts use the 24-SOIC package with identical dimensions (0.295" width, 7.50mm). Pin assignments and functionality are equivalent, allowing direct PCB substitution without layout modifications.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the 74HCT4515D,652 and CD74HC4515M are ROHS3 compliant with MSL 1 rating, ensuring compatibility with standard manufacturing processes and storage requirements.

Q: Why is the original part listed as Obsolete?

A: The 74HCT4515D,652 has reached end-of-life status with NXP. The CD74HC4515M from Texas Instruments provides continued availability of equivalent functionality, though it is also classified as Last Time Buy, indicating limited future availability.
