Key Parameters

Substitute Part Grouping Explanation

Substitution for the 74HC4514D,652 is based on the following critical parameters that must remain constant across equivalent parts:

• Base product number: 74HC4514
• Decoder/demultiplexer function with 1 x 4:16 circuit configuration
• 24-SOIC package with 0.295" (7.50mm) width
• Surface mount mounting type
• Single supply voltage operation (2V ~ 6V range)
• Output current specifications: 5.2mA high and low
• RoHS3 compliance and REACH unaffected status

The substitute parts listed below maintain these electrical and mechanical specifications while offering improved product status and availability through alternative manufacturers.

Parameter Comparison

Engineering Selection Recommendations

CD74HC4514M96 is the primary substitute for new designs and ongoing procurement. This part maintains active product status from Texas Instruments, ensuring long-term availability and supply chain stability. The extended operating temperature range (-55°C ~ 125°C) provides additional margin beyond the original specification (-40°C ~ 125°C). All electrical parameters, package specifications, and compliance certifications (ROHS3, REACH unaffected) are identical to the original part.

CD74HC4514M serves as an alternative substitute with last-time-buy status from Texas Instruments. This part is electrically and mechanically equivalent to CD74HC4514M96 but with limited future availability.

Both Texas Instruments alternatives are direct functional replacements suitable for PCB assembly without design modification, as they share identical pinout, package dimensions, and electrical characteristics with the Nexperia original.

Frequently Asked Questions (FAQ)

Q: Can CD74HC4514M96 be used as a direct replacement for 74HC4514D,652 without PCB modifications?

A: Yes. Both parts use the 24-SOIC package with identical pin assignments, dimensions (0.295" width, 7.50mm), and electrical specifications. No PCB layout changes are required.

Q: What is the difference between CD74HC4514M and CD74HC4514M96?

A: Both parts are electrically identical with the same 1 x 4:16 decoder/demultiplexer function and 24-SOIC package. The primary difference is product status: CD74HC4514M is last-time-buy, while CD74HC4514M96 is active. CD74HC4514M96 is recommended for new designs due to ongoing availability.

Q: Are the operating temperature ranges compatible?

A: The original 74HC4514D,652 operates from -40°C to 125°C. Both Texas Instruments substitutes operate from -55°C to 125°C, providing an extended lower temperature range. This is compatible with the original specification and suitable for applications requiring the original temperature range.

Q: Do the substitute parts meet the same compliance requirements?

A: Yes. Both CD74HC4514M and CD74HC4514M96 are ROHS3 compliant and REACH unaffected, matching the original part's compliance status.

Q: What packaging options are available for the substitutes?

A: CD74HC4514M is supplied in tube packaging. CD74HC4514M96 is supplied in cut tape and Digi-Reel format. Both are surface mount 24-SOIC packages suitable for automated assembly.
