MC74ACT153D Equivalent & Substitute Parts

Part Overview

The MC74ACT153D is a 2 x 4:1 multiplexer logic integrated circuit manufactured by onsemi in a 16-SOIC surface mount package. This part is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement. The MC74ACT153D operates from a single 4.5V to 5.5V supply with output currents of 24mA (high and low) and supports operating temperatures from -40°C to 85°C. Identifying compatible alternatives ensures design continuity and supply chain flexibility.

Substitute Part Grouping Explanation

Substitution for the MC74ACT153D is determined by the following critical parameters: circuit configuration (2 x 4:1 multiplexer), package type (16-SOIC), voltage supply range (4.5V ~ 5.5V), output current capability (24mA), and mounting type (surface mount). Parts are grouped into three categories based on their relationship to the main part:

Direct Manufacturer Equivalents maintain identical electrical specifications and package footprint, differing only in manufacturer or product status.

Similar Equivalents meet all electrical and mechanical requirements but may have extended operating temperature ranges or different compliance certifications.

Parametric Equivalents share the same base product series and electrical characteristics but use different part number designations within the same manufacturer family.

Parameter Comparison

Engineering Selection Recommendations

MC74ACT153DG (onsemi) is the primary direct substitute. It maintains identical electrical specifications and package footprint while offering active product status and ROHS3 compliance, making it suitable for new designs and ongoing production.

CD74ACT153M96 (Texas Instruments) provides an alternative from an established manufacturer with active product status and ROHS3 compliance. The extended operating temperature range (-55°C ~ 125°C) accommodates more demanding thermal environments compared to the original part's -40°C ~ 85°C specification.

CD74ACT153M (Harris Corporation) is electrically equivalent but carries obsolete status, limiting its suitability for new procurement unless legacy support is required.

MC74ACT253DG (onsemi) is a parametric equivalent within the 74ACT series. While it maintains the same electrical characteristics and package, the different base product number (74ACT253 versus 74ACT153) indicates a distinct part designation and should be verified for functional equivalence in specific circuit applications.

Frequently Asked Questions (FAQ)

Q: Can MC74ACT153DG directly replace MC74ACT153D? A: Yes. MC74ACT153DG is a direct substitute with identical electrical specifications (4.5V ~ 5.5V supply, 24mA output current, 2 x 4:1 multiplexer configuration) and 16-SOIC package. The primary differences are active product status and ROHS3 compliance.

Q: What is the difference between CD74ACT153M and CD74ACT153M96? A: Both are 2 x 4:1 multiplexers in 16-SOIC packages with identical electrical specifications. CD74ACT153M96 is the active product from Texas Instruments with ROHS3 compliance, while CD74ACT153M (Harris Corporation) is obsolete. The "96" suffix indicates Texas Instruments' packaging designation.

Q: Does the extended temperature range of CD74ACT153M96 affect compatibility? A: No. The CD74ACT153M96 operating range of -55°C ~ 125°C is a superset of the original MC74ACT153D range (-40°C ~ 85°C). This provides greater thermal margin and does not compromise compatibility in applications within the original temperature specification.

Q: Are all substitute parts in the same 16-SOIC package? A: Yes. All listed substitutes use the 16-SOIC (0.154", 3.90mm Width) package, ensuring identical PCB footprint and mounting compatibility.

Q: What is the significance of ROHS3 compliance? A: ROHS3 compliance indicates conformance to current Restriction of Hazardous Substances regulations. MC74ACT153DG and CD74ACT153M96 meet this requirement, while the original MC74ACT153D does not. For new designs and regulated markets, ROHS3-compliant alternatives are recommended.

Q: Is MC74ACT253DG functionally identical to MC74ACT153D? A: Both are 2 x 4:1 multiplexers with identical electrical specifications and 16-SOIC packages. However, the different base product numbers (74ACT253 versus 74ACT153) indicate distinct part designations. Functional equivalence should be confirmed through datasheet comparison before substitution in critical applications.
