Key Parameters

Substitute Part Grouping Explanation

Substitution of the 74ABT652CMSA is determined by strict equivalence across the following critical parameters:

• Logic type and function: Non-inverting transceiver architecture
• Data width: 8-bit per element configuration
• Output configuration: 3-state output capability
• Electrical specifications: 32mA/64mA output current ratings and 4.5V–5.5V supply voltage range
• Package form factor: 24-SSOP surface mount package with identical 5.30mm width
• Operating temperature range: -40°C to 85°C

The SN74ABT652ADBR from Texas Instruments meets all these criteria and qualifies as a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

The SN74ABT652ADBR is the appropriate substitute for the obsolete 74ABT652CMSA. This recommendation is based on:

• Complete electrical and functional equivalence across all specified parameters
• Active product status of the substitute, ensuring continued availability and manufacturing support
• Identical package geometry and mounting requirements, enabling direct PCB-level replacement
• Equivalent regulatory compliance: both parts maintain REACH Unaffected status and EAR99 export classification
• Identical moisture sensitivity rating (MSL 1), confirming equivalent handling and storage requirements

The Texas Instruments device is available in Tape & Reel packaging, suitable for automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the SN74ABT652ADBR be used as a direct replacement for the 74ABT652CMSA?

A: Yes. Both parts are electrically and functionally identical across all specified parameters, including logic type, bit width, output current ratings, supply voltage range, operating temperature, and package form factor. No circuit modifications are required.

Q: Are there any differences in packaging between these parts?

A: Both parts use the 24-SSOP surface mount package with identical dimensions (0.209" width, 5.30mm). The primary packaging difference is that the SN74ABT652ADBR is supplied in Tape & Reel format, while the 74ABT652CMSA was available in standard packaging. This difference does not affect electrical performance or PCB compatibility.

Q: Why is the 74ABT652CMSA classified as obsolete?

A: The onsemi part has reached end-of-life status. The SN74ABT652ADBR from Texas Instruments remains in active production, making it the recommended choice for new designs and ongoing system support.

Q: Are the compliance certifications equivalent?

A: Yes. Both parts share identical REACH status (REACH Unaffected), ECCN classification (EAR99), and moisture sensitivity level (MSL 1). No additional compliance documentation is required when substituting between these parts.

Q: What is the supply voltage tolerance for these transceivers?

A: Both parts operate within a 4.5V to 5.5V supply voltage range. Ensure your system power supply remains within this specification for reliable operation.
