74ACTQ153SC Equivalent & Substitute Parts

Part Overview

The 74ACTQ153SC is a dual 4:1 multiplexer logic integrated circuit manufactured by onsemi in a 16-SOIC surface mount package. This component functions as a data selector, routing one of four input signals to a single output based on control logic inputs. The part is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement.

Substitute Part Grouping Explanation

Substitution for the 74ACTQ153SC is determined by strict equivalence across the following parameters: multiplexer circuit configuration (2 x 4:1), output current capability (24mA high and low), supply voltage range (4.5V ~ 5.5V), package type (16-SOIC), and mounting method (surface mount). All substitute parts listed maintain these core electrical and mechanical specifications, ensuring functional interchangeability in circuit applications.

The substitute parts are grouped into two categories: direct equivalents from alternative manufacturers (CD74ACT153M, CD74ACT153M96) and parametric equivalents from onsemi (MC74ACT153DG, MC74ACT253DG). Differences in operating temperature range, product status, and compliance certifications do not affect functional substitution but may influence selection based on application requirements.

Parameter Comparison

Engineering Selection Recommendations

For new designs and long-term procurement, CD74ACT153M96 (Texas Instruments) is the preferred substitute. This part maintains full electrical equivalence while offering active product status and ROHS3 compliance, ensuring continued availability and regulatory alignment.

MC74ACT153DG (onsemi) provides an alternative from the original manufacturer with active status and equivalent operating specifications within the -40°C to 85°C range, matching the thermal performance of the 74ACTQ153SC.

CD74ACT153M (Harris Corporation) and MC74ACT253DG (onsemi) are functionally equivalent but carry obsolete status. These parts are suitable only for legacy system maintenance or where existing inventory is available.

Frequently Asked Questions (FAQ)

Q: Can CD74ACT153M96 directly replace 74ACTQ153SC in existing designs? A: Yes. Both parts share identical multiplexer configuration (2 x 4:1), output current ratings (24mA), supply voltage range (4.5V ~ 5.5V), and 16-SOIC package. Electrical and mechanical compatibility is complete.

Q: What is the difference between MC74ACT153DG and MC74ACT253DG? A: Both are onsemi products with identical electrical specifications and operating temperature range (-40°C ~ 85°C). The primary difference is product status: MC74ACT153DG is active, while MC74ACT253DG is obsolete. For new applications, MC74ACT153DG is preferred.

Q: Why do some substitutes have wider operating temperature ranges? A: CD74ACT153M and CD74ACT153M96 specify -55°C ~ 125°C operating temperature, compared to -40°C ~ 85°C for the 74ACTQ153SC. This wider range does not affect substitution; the parts remain functionally equivalent. Selection should be based on application temperature requirements.

Q: Are there packaging differences between substitute parts? A: All substitute parts use the 16-SOIC surface mount package with identical dimensions (0.154", 3.90mm width). Packaging is fully compatible across all listed alternatives.

Q: Which substitute part has the best compliance status? A: CD74ACT153M96 and MC74ACT153DG both carry ROHS3 compliance and active product status, making them suitable for applications requiring regulatory compliance and long-term availability assurance.
