MC74ACT253DR2 Equivalent & Substitute Parts

Part Overview

The MC74ACT253DR2 is a dual 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 device functions as a 2 x 4:1 multiplexer with three-state outputs, suitable for data selection and routing applications in digital logic circuits.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the MC74ACT253DR2 is determined by the following critical parameters:

• Circuit Configuration: 2 x 4:1 multiplexer topology
• Package Type: 16-SOIC surface mount package with identical physical dimensions
• Voltage Supply Range: 4.5V ~ 5.5V single supply operation
• Functional Equivalence: Dual 4:1 multiplexer with three-state outputs
• Pin Compatibility: Identical pinout within the 16-SOIC package

Substitute parts are grouped into two categories:

Direct Manufacturer Equivalents maintain identical electrical specifications and are sourced from the same or alternative manufacturers with active product status.

Parametric Equivalents provide the same functional multiplexer configuration with compatible electrical characteristics, though they may originate from different base product numbers within the same logic family.

Parameter Comparison

Engineering Selection Recommendations

MC74ACT253DR2G (onsemi) is the primary direct substitute. It maintains identical electrical specifications and package configuration as the obsolete MC74ACT253DR2, with the advantage of active product status and ROHS3 compliance. This part is recommended for designs requiring exact parameter matching and onsemi sourcing continuity.

MC74ACT153DR2G (onsemi) provides parametric equivalence with identical electrical performance and package compatibility. Although derived from a different base product number (74ACT153 versus 74ACT253), it delivers the same 2 x 4:1 multiplexer functionality and is actively manufactured with ROHS3 compliance.

CD74ACT253M96 (Texas Instruments) offers functional substitution with enhanced electrical performance. This part provides higher output current capability (75mA versus 24mA) and an extended operating temperature range (-55°C ~ 125°C versus -40°C ~ 85°C), making it suitable for applications requiring greater thermal margin or increased drive capability. ROHS3 compliance is confirmed.

Selection should prioritize active product status and ROHS3 compliance for new designs. The choice between onsemi and Texas Instruments sources depends on supply chain requirements and design specifications for output current and temperature range.

Frequently Asked Questions (FAQ)

Q: Can MC74ACT253DR2G directly replace MC74ACT253DR2?

A: Yes. MC74ACT253DR2G is a direct equivalent with identical circuit configuration (2 x 4:1 multiplexer), package type (16-SOIC), voltage supply range (4.5V ~ 5.5V), and output current specifications (24mA, 24mA). The primary difference is product status (active versus obsolete) and RoHS compliance.

Q: What is the difference between MC74ACT253DR2G and MC74ACT153DR2G?

A: Both parts are 2 x 4:1 multiplexers in 16-SOIC packages with identical electrical specifications. The difference lies in the base product number designation (253 versus 153). Both are functionally equivalent and pin-compatible for this application.

Q: When should CD74ACT253M96 be selected instead of the onsemi alternatives?

A: CD74ACT253M96 should be selected when the design requires higher output current (75mA versus 24mA) or extended operating temperature range (-55°C ~ 125°C versus -40°C ~ 85°C). This part is manufactured by Texas Instruments and maintains the same 16-SOIC package and 2 x 4:1 multiplexer configuration.

Q: Are all substitute parts available in the same packaging format?

A: Yes. All substitute parts are available in 16-SOIC surface mount packages with identical physical dimensions (0.154", 3.90mm width). Packaging format differences relate to tape and reel versus bulk options, which do not affect electrical or mechanical compatibility.

Q: What is the RoHS compliance status of these parts?

A: MC74ACT253DR2 is RoHS non-compliant. All active substitute parts (MC74ACT253DR2G, MC74ACT153DR2G, and CD74ACT253M96) are ROHS3 compliant, meeting current environmental and regulatory requirements.

Q: Are these parts suitable for new design implementations?

A: MC74ACT253DR2G, MC74ACT153DR2G, and CD74ACT253M96 are all suitable for new designs. All three maintain active product status and ROHS3 compliance. Selection should be based on specific requirements for output current capability, operating temperature range, and manufacturer sourcing preferences.
