CD74ACT652M Equivalent & Substitute Parts

Part Overview

The CD74ACT652M is a non-inverting transceiver logic integrated circuit manufactured by Texas Instruments, designed for 8-bit data transmission with 3-state output capability. This device operates within a 4.5V to 5.5V supply voltage range and is housed in a 24-SOIC surface mount package. The part is currently in Last Time Buy status, indicating discontinued production. Identifying equivalent and substitute parts is necessary to ensure design continuity and maintain supply chain reliability for applications requiring this transceiver functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CD74ACT652M are classified based on strict alignment with the following critical parameters: logic type (non-inverting transceiver), element and bit configuration (1 element, 8 bits per element), output type (3-state), current drive capability (24mA output high and low), supply voltage range (4.5V ~ 5.5V), package type (24-SOIC), and mounting method (surface mount). All identified substitutes maintain these core electrical and mechanical specifications, ensuring functional compatibility within the 74ACT logic family. Variations in product status, packaging format (tube versus tape & reel), manufacturer, and operating temperature range are noted but do not affect the core substitution relationship.

Parameter Comparison

Engineering Selection Recommendations

CD74ACT652M96 is the primary recommended substitute. This part is manufactured by Texas Instruments, maintains identical electrical specifications and package geometry, and carries Active product status with ROHS3 compliance. The only difference is packaging format (Tape & Reel versus Tube) and MSL rating (both Level 1). This part provides the highest compatibility and supply continuity.

CD74ACT646M is a parametric equivalent that maintains all core electrical and mechanical specifications. However, this part is manufactured by Harris Corporation and carries Obsolete status with RoHS non-compliance, limiting its suitability for new designs or applications with regulatory requirements.

MC74ACT652DWR2G is manufactured by onsemi and maintains ROHS3 compliance and core electrical specifications. This part has Obsolete status and a reduced operating temperature range (-40°C to 85°C versus -55°C to 125°C), which may restrict use in extended temperature applications. MSL rating is Level 3, requiring controlled storage conditions.

Frequently Asked Questions (FAQ)

Q: Can CD74ACT652M96 be used as a direct replacement for CD74ACT652M?

A: Yes. CD74ACT652M96 is functionally equivalent with identical electrical parameters, supply voltage, current drive, output type, and package dimensions. The difference in packaging format (Tape & Reel versus Tube) does not affect circuit performance.

Q: What is the significance of the operating temperature range difference in MC74ACT652DWR2G?

A: MC74ACT652DWR2G operates from -40°C to 85°C, compared to the -55°C to 125°C range of the main part. Applications requiring operation below -40°C or above 85°C cannot use this substitute.

Q: Why is CD74ACT646M listed as a substitute if it is obsolete?

A: CD74ACT646M maintains all critical electrical and mechanical parameters required for functional substitution. However, its Obsolete status and RoHS non-compliance make it unsuitable for new designs or regulated applications.

Q: Does packaging format affect circuit compatibility?

A: No. Tube and Tape & Reel packaging formats contain identical die and lead configurations. The difference is in handling and storage format only. Both formats are compatible with standard surface mount assembly processes.

Q: What does MSL Level 1 versus Level 3 mean for component handling?

A: MSL (Moisture Sensitivity Level) 1 indicates unlimited shelf life without moisture control. MSL 3 requires controlled storage conditions and has a 168-hour floor life after opening. Components with higher MSL ratings require more stringent handling procedures.

Q: Are all substitutes ROHS3 compliant?

A: No. CD74ACT646M is RoHS non-compliant. CD74ACT652M96 and MC74ACT652DWR2G are both ROHS3 compliant. Regulatory requirements may restrict substitute selection.
