MC74ACT253D Equivalent & Substitute Parts

Part Overview

The MC74ACT253D is a 2 x 4:1 multiplexer logic integrated circuit manufactured by onsemi in a 16-SOIC surface mount package. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement. The MC74ACT253D operates from a single 4.5V to 5.5V supply and is suitable for applications requiring multiplexing functionality in the 74ACT logic family.

Substitute Part Grouping Explanation

Substitution for the MC74ACT253D 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), and mounting type (surface mount). Parts are grouped into three categories based on their relationship to the main part:

Direct Manufacturer Equivalent: Parts with identical base product numbers and electrical specifications from the same manufacturer.

Similar Manufacturer Parts: Parts from different manufacturers with the same circuit configuration and package, but with enhanced electrical performance (higher output current and extended temperature range).

Parametric Equivalent: Parts with different base product numbers but matching electrical and mechanical parameters within the allowed substitution criteria.

Parameter Comparison

Engineering Selection Recommendations

MC74ACT253DG is the direct onsemi equivalent with improved RoHS3 compliance status while maintaining identical electrical specifications and operating parameters.

CD74ACT253M96 from Texas Instruments is the preferred long-term substitute, offering active product status, RoHS3 compliance, enhanced output current capability (75mA versus 24mA), and extended operating temperature range (-55°C to 125°C). This part is suitable for applications requiring higher current drive or wider temperature operation.

MC74ACT153DG from onsemi provides active product status and RoHS3 compliance with matching electrical specifications to the original part, making it suitable for direct replacement in designs where the base product number change is acceptable.

CD74ACT253M from Harris Corporation offers enhanced electrical performance but retains obsolete status and non-compliant RoHS rating, limiting its suitability for new designs.

Frequently Asked Questions (FAQ)

Q: Can MC74ACT253DG be used as a direct replacement for MC74ACT253D?

A: Yes. MC74ACT253DG is the direct onsemi equivalent with identical circuit configuration, package, voltage supply, output current, and operating temperature specifications. The primary difference is improved RoHS3 compliance status.

Q: What are the advantages of CD74ACT253M96 over the original MC74ACT253D?

A: CD74ACT253M96 provides active product status (versus obsolete), RoHS3 compliance, higher output current (75mA versus 24mA), and extended operating temperature range (-55°C to 125°C versus -40°C to 85°C). These enhancements support long-term availability and operation in demanding thermal environments.

Q: Are all substitute parts pin-compatible with MC74ACT253D?

A: All listed substitutes share the 16-SOIC package format with identical pinout. Pin compatibility is maintained across all substitute parts.

Q: What is the difference between MC74ACT253DG and MC74ACT153DG?

A: Both parts are onsemi products with identical electrical specifications and 16-SOIC packaging. The primary difference is the base product number (74ACT253 versus 74ACT153). MC74ACT153DG offers active product status and RoHS3 compliance.

Q: Which substitute is recommended for new designs?

A: CD74ACT253M96 from Texas Instruments is recommended for new designs due to its active product status, RoHS3 compliance, and enhanced electrical performance characteristics.

Q: Does packaging format differ between substitutes?

A: All substitutes use the 16-SOIC surface mount package. Packaging options vary by supplier (tube, tape & reel), but the physical package dimensions remain consistent at 0.154" width (3.90mm).
