Key Parameters

Substitute Part Grouping Explanation

Substitution for the CD74HC4514E is determined by functional equivalence across the following critical parameters:

• Base Product Number: Must be 74HC4514 to ensure identical decoder/demultiplexer functionality
• Circuit Configuration: Must maintain 1 x 4:16 decoding capability
• Electrical Specifications: Output current (5.2mA, 5.2mA), supply voltage range (2V ~ 6V), and operating temperature range (-55°C ~ 125°C) must be identical or superior
• Compliance & Certifications: RoHS3 compliance and MSL rating must be maintained

The primary substitute identified is the CD74HC4514M96, which shares the identical base product number, circuit configuration, and electrical specifications. The key difference is the package type: the substitute uses surface-mount 24-SOIC packaging instead of through-hole 24-DIP packaging. This substitution is valid when PCB design accommodates surface-mount technology.

Parameter Comparison

Engineering Selection Recommendations

The CD74HC4514M96 is the direct functional equivalent of the CD74HC4514E. Both devices maintain identical electrical performance, compliance certifications, and operational specifications. The CD74HC4514M96 carries an active product status, ensuring continued availability and manufacturing support from Texas Instruments.

Selection between these parts depends solely on PCB design requirements:

• CD74HC4514E (24-DIP): Select when through-hole mounting is required or when existing PCB layouts are designed for DIP packages.
• CD74HC4514M96 (24-SOIC): Select for new designs or PCB revisions that accommodate surface-mount technology, offering reduced board space and improved manufacturing efficiency.

Both parts maintain ROHS3 compliance and unlimited moisture sensitivity rating, ensuring compatibility with modern manufacturing and environmental standards.

Frequently Asked Questions (FAQ)

Q: Can the CD74HC4514M96 directly replace the CD74HC4514E in existing designs?

A: Electrical and functional replacement is direct. However, PCB layout modification is required due to package differences. The CD74HC4514E uses 24-DIP through-hole mounting, while the CD74HC4514M96 uses 24-SOIC surface-mount packaging. Pin-to-pin functionality is identical, but physical footprints differ.

Q: Are there any electrical performance differences between these parts?

A: No. Both devices share identical output current specifications (5.2mA, 5.2mA), supply voltage range (2V ~ 6V), and operating temperature range (-55°C ~ 125°C). Functional performance is equivalent.

Q: Why is the CD74HC4514E listed as obsolete?

A: The CD74HC4514E (24-DIP package) is obsolete due to industry-wide transition toward surface-mount technology. The CD74HC4514M96 (24-SOIC package) represents the active equivalent in the 74HC4514 product line.

Q: Do both parts meet current compliance requirements?

A: Yes. Both the CD74HC4514E and CD74HC4514M96 are ROHS3 compliant with MSL rating of 1 (Unlimited), meeting current environmental and manufacturing standards.

Q: What is the pin count for both packages?

A: Both devices feature 24 pins. The CD74HC4514E uses a 24-pin DIP package (0.600" width), while the CD74HC4514M96 uses a 24-pin SOIC package (0.295" width).
