CD74ACT253M Equivalent & Substitute Parts

Part Overview

The CD74ACT253M 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 and the necessity to identify equivalent alternatives for ongoing design requirements and production planning. The CD74ACT253M operates with single supply voltage between 4.5V and 5.5V, making it suitable for standard logic applications requiring multiplexing functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CD74ACT253M is determined by the following critical parameters: identical circuit configuration (2 x 4:1 multiplexer), compatible package type (16-SOIC), matching voltage supply range (4.5V ~ 5.5V), and compliance certifications (ROHS3, REACH Unaffected). The substitute parts identified maintain the same functional circuit topology and physical package dimensions, ensuring mechanical and electrical compatibility in PCB layouts and system designs.

The identified substitutes are grouped based on manufacturer and product status:

• Texas Instruments CD74ACT253M96: Identical electrical specifications with Tape & Reel packaging variant
• onsemi MC74ACT253DG: Functionally equivalent with reduced output current specifications and narrower operating temperature range
• onsemi MC74ACT253DR2G: Functionally equivalent with reduced output current specifications, narrower operating temperature range, and Tape & Reel packaging

Parameter Comparison

Engineering Selection Recommendations

CD74ACT253M96 is the primary recommended substitute. This part maintains identical electrical specifications including output current ratings (75mA / 75mA) and operating temperature range (-55°C ~ 125°C) as the original CD74ACT253M. The only difference is packaging format (Tape & Reel versus Tube), which does not affect functional performance. Product status is Active, ensuring continued availability and supply chain stability.

MC74ACT253DR2G is an alternative substitute suitable for applications where reduced output current (24mA / 24mA) and narrower operating temperature range (-40°C ~ 85°C) are acceptable. This part is manufactured by onsemi and maintains Active product status with Tape & Reel packaging. Selection of this substitute requires verification that system designs do not depend on the higher output current or extended temperature performance of the original part.

MC74ACT253DG is not recommended for new designs due to Obsolete product status, despite functional equivalence. This part should be considered only for legacy system maintenance where supply chain alternatives are unavailable.

Frequently Asked Questions (FAQ)

Q: Can CD74ACT253M96 be used as a direct replacement for CD74ACT253M?

A: Yes. CD74ACT253M96 is electrically and mechanically identical to CD74ACT253M. The difference is packaging format: CD74ACT253M is supplied in Tube packaging while CD74ACT253M96 is supplied in Tape & Reel format. Both are 16-SOIC surface mount packages with identical pin configurations and electrical performance.

Q: What are the limitations of using MC74ACT253DR2G as a substitute?

A: MC74ACT253DR2G has two parameter differences: output current is reduced from 75mA to 24mA per output, and operating temperature range is narrowed from -55°C ~ 125°C to -40°C ~ 85°C. Applications requiring higher output current or operation at temperatures below -40°C or above 85°C are not compatible with this substitute.

Q: Why is MC74ACT253DG listed if it is Obsolete?

A: MC74ACT253DG is included for reference in legacy system documentation and maintenance scenarios. For new designs and production, MC74ACT253DR2G (Active status) is the preferred onsemi alternative.

Q: Are all substitutes ROHS3 compliant?

A: Yes. All listed substitutes (CD74ACT253M96, MC74ACT253DG, MC74ACT253DR2G) are ROHS3 Compliant and REACH Unaffected, matching the compliance status of the original CD74ACT253M.

Q: Does package format affect circuit performance?

A: No. Tube and Tape & Reel packaging formats contain identical die and internal circuitry. The packaging difference affects only handling, storage, and automated assembly processes, not electrical or functional performance.
