MC74ACT652DW Equivalent & Substitute Parts

Part Overview

The MC74ACT652DW is a non-inverting transceiver logic IC manufactured by onsemi, designed for 8-bit bidirectional data transfer with 3-state output capability. Operating within a 4.5V to 5.5V supply range, this component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MC74ACT652DW are classified based on strict electrical and mechanical compatibility criteria. All substitute candidates maintain identical functional specifications across the following critical parameters:

• Logic Type: Transceiver, Non-Inverting
• Number of Elements: 1
• Number of Bits per Element: 8
• Output Type: 3-State
• Current - Output High, Low: 24mA, 24mA
• Voltage - Supply: 4.5V ~ 5.5V
• Package / Case: 24-SOIC (0.295", 7.50mm Width)
• Mounting Type: Surface Mount

Substitutes are grouped into two categories: Direct Manufacturer Equivalent and Parametric Equivalent. Direct equivalents share identical part numbering within the 74ACT652 base series. Parametric equivalents maintain all critical electrical and mechanical parameters while originating from different base product numbers within the 74ACT logic family.

Engineering Selection Recommendations

CD74ACT652M96 (Direct Manufacturer Equivalent - Recommended Primary Choice)

This Texas Instruments part maintains identical electrical and mechanical specifications to the MC74ACT652DW while offering active product status and ROHS3 compliance. The extended operating temperature range (-55°C ~ 125°C) provides additional thermal margin. Packaging is supplied in Tape & Reel format, suitable for automated assembly processes.

74ACT11245DW (Parametric Equivalent - Secondary Choice)

This Texas Instruments part satisfies all critical electrical and mechanical parameters with ROHS3 compliance. Product status is Last Time Buy, indicating limited future availability. Operating temperature range matches the original specification (-40°C ~ 85°C).

MC74ACT646DWG (Parametric Equivalent - Tertiary Option)

This onsemi part maintains electrical compatibility and ROHS3 compliance. Product status is obsolete, similar to the original part. Moisture Sensitivity Level is rated at 3 (168 Hours), requiring controlled storage conditions compared to the unlimited MSL of other options.

Frequently Asked Questions (FAQ)

Q: Can CD74ACT652M96 be used as a direct replacement for MC74ACT652DW?

A: Yes. Both parts share identical logic type, element count, bit width, output type, current ratings, supply voltage, and 24-SOIC package specifications. The CD74ACT652M96 offers improved product status (Active vs. Obsolete) and ROHS3 compliance.

Q: What is the difference between direct equivalents and parametric equivalents?

A: Direct equivalents share the same base product number (74ACT652) and are manufactured variants of the same design. Parametric equivalents originate from different base product numbers (74ACT11245, 74ACT646) but maintain identical electrical and mechanical parameters required for functional substitution.

Q: Does the extended temperature range of CD74ACT652M96 affect compatibility?

A: No. The extended operating temperature range (-55°C ~ 125°C) of CD74ACT652M96 is a superset of the original specification (-40°C ~ 85°C), ensuring full compatibility within the original design envelope.

Q: What is the significance of Moisture Sensitivity Level (MSL) differences?

A: MC74ACT646DWG has MSL 3 (168 Hours), requiring storage in controlled humidity conditions. CD74ACT652M96 and 74ACT11245DW have MSL 1 (Unlimited), allowing standard storage without moisture control requirements.

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

A: All substitute parts use 24-SOIC surface mount packaging. CD74ACT652M96 is supplied in Tape & Reel format for automated assembly. Packaging format does not affect electrical or mechanical compatibility.

Q: Why is RoHS compliance important for this substitution?

A: The original MC74ACT652DW is RoHS non-compliant. Substitute parts with ROHS3 compliance (CD74ACT652M96, 74ACT11245DW, MC74ACT646DWG) meet current environmental and regulatory requirements for new designs and procurement.
