CD74HCT253M Equivalent & Substitute Parts

Part Overview

The CD74HCT253M is a 2 x 4:1 multiplexer logic integrated circuit manufactured by Texas Instruments in a 16-SOIC surface mount package. This component is classified as Last Time Buy, indicating limited availability from the original manufacturer. The CD74HCT253M operates with a single supply voltage between 4.5V and 5.5V and supports a wide operating temperature range from -55°C to 125°C. Due to its Last Time Buy status, equivalent and substitute parts are necessary for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the CD74HCT253M is determined by the following critical parameters: circuit configuration (2 x 4:1 multiplexer), package type (16-SOIC), supply voltage range (4.5V ~ 5.5V), and mounting method (surface mount). All substitute parts maintain these core electrical and mechanical specifications.

Substitute parts are grouped into two categories:

Manufacturer Recommended Substitutes maintain identical or superior electrical performance and compliance certifications. These parts are sourced from authorized manufacturers and support direct replacement in production environments.

Parametric Equivalents provide functional compatibility through matching circuit topology and electrical parameters, though they may differ in product status, packaging format, or compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

For Active Production: The 74HCT253D,653 (Nexperia) and 74HCT253D-Q100,118 (NXP) are the preferred substitutes. Both parts are in Active product status with ROHS3 compliance. The 74HCT253D-Q100,118 includes AEC-Q100 automotive qualification, suitable for applications requiring automotive-grade components. Both parts provide higher output current capability (6mA vs. 4mA) and maintain the required voltage supply and package specifications.

For Legacy System Support: The CD74HCT253M96 (Texas Instruments) provides direct compatibility with identical electrical specifications and RoHS3 compliance, though it carries Obsolete product status. The CD74HCT153M (Harris Corporation) offers parametric equivalence but is RoHS non-compliant and should be evaluated against regulatory requirements.

Temperature Consideration: The CD74HCT253M supports -55°C to 125°C operation. Active substitutes (74HCT253D,653 and 74HCT253D-Q100,118) operate from -40°C to 125°C. Applications requiring the full -55°C lower temperature limit must use the original part or the CD74HCT253M96.

Frequently Asked Questions (FAQ)

Q: Can 74HCT253D,653 directly replace CD74HCT253M in all applications?

A: Yes, for applications operating above -40°C. Both parts share identical circuit topology (2 x 4:1 multiplexer), package (16-SOIC), and supply voltage range (4.5V ~ 5.5V). The 74HCT253D,653 provides higher output current (6mA vs. 4mA), which is compatible with the original specification. Applications requiring operation below -40°C must use CD74HCT253M or CD74HCT253M96.

Q: What is the difference between 74HCT253D,653 and 74HCT253D-Q100,118?

A: Both parts are electrically and functionally identical with matching circuit topology, package, and electrical parameters. The 74HCT253D-Q100,118 includes AEC-Q100 automotive qualification and is supplied in Bulk packaging, while 74HCT253D,653 is supplied in Tape & Reel format. Selection depends on packaging requirements and automotive qualification needs.

Q: Why is CD74HCT153M listed as a parametric equivalent rather than a direct substitute?

A: The CD74HCT153M maintains identical electrical specifications and package type but carries RoHS non-compliant status, whereas the original CD74HCT253M is ROHS3 compliant. This compliance difference requires evaluation against application regulatory requirements before selection.

Q: Are there packaging format differences between substitute parts?

A: Yes. CD74HCT253M is supplied in Tube packaging. CD74HCT253M96 is available in Cut Tape (CT) & Digi-Reel format. 74HCT253D,653 is supplied in Tape & Reel (TR). 74HCT253D-Q100,118 is supplied in Bulk. All parts use identical 16-SOIC surface mount packages and are compatible for PCB assembly.

Q: Can I use CD74HCT153M as a substitute?

A: The CD74HCT153M provides parametric equivalence with matching circuit topology and electrical specifications. However, it is RoHS non-compliant and Obsolete. Use only if regulatory requirements permit non-compliant components and availability can be confirmed.
