Key Parameters

Substitute Part Grouping Explanation

Substitution of the SN74AS760NSE4 is determined by strict equivalence across all electrical and mechanical parameters. The following criteria establish valid substitutes:

Electrical Equivalence Requirements:

• Logic Type: Buffer, Non-Inverting
• Number of Elements: 2
• Number of Bits per Element: 4
• Output Type: Open Collector
• Current - Output Low: 64mA
• Voltage - Supply: 4.5V ~ 5.5V
• Operating Temperature: 0°C ~ 70°C (TA)

Mechanical Equivalence Requirements:

• Package / Case: 20-SOIC (0.209", 5.30mm Width)
• Mounting Type: Surface Mount
• Base Product Number: 74AS760

Compliance Requirements:

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

The SN74AS760NSE4 differs from its substitutes only in packaging format (Tube) and product status (Last Time Buy). All substitute parts maintain identical electrical performance and mechanical compatibility.

Engineering Selection Recommendations

SN74AS760NSR (Primary Substitute)

The SN74AS760NSR is the manufacturer-recommended substitute for the SN74AS760NSE4. This part maintains identical electrical and mechanical specifications while offering Active product status, ensuring long-term availability and supply chain stability. The SN74AS760NSR is supplied in Tape & Reel (TR) packaging format, which is standard for high-volume manufacturing and automated assembly processes. All compliance certifications, including ROHS3 and MSL Level 1, are maintained. This part is suitable for new designs and production environments requiring continuous component availability.

SN74AS760NS (Secondary Substitute)

The SN74AS760NS provides functional equivalence to the SN74AS760NSE4 with identical electrical performance and mechanical compatibility. Both parts share Last Time Buy product status, indicating limited remaining inventory. The SN74AS760NS is supplied in Tube packaging format, matching the original part's packaging specification. This substitute is appropriate for applications where existing supply channels or assembly processes are optimized for tube-packaged components. Compliance certifications remain equivalent across all parameters.

Selection Criteria

Component selection between these substitutes depends on packaging requirements and supply chain considerations. The SN74AS760NSR is recommended for applications prioritizing long-term availability and automated assembly compatibility. The SN74AS760NS is suitable when tube packaging aligns with existing procurement or assembly specifications. All three parts deliver identical electrical performance and operate within the same environmental and compliance parameters.

Frequently Asked Questions (FAQ)

Q: Are the SN74AS760NSR and SN74AS760NS electrically identical to the SN74AS760NSE4?

A: Yes. All three parts share identical electrical specifications, including logic type (non-inverting buffer), element configuration (2 elements, 4 bits per element), output type (open collector), output current (64mA), supply voltage range (4.5V to 5.5V), and operating temperature range (0°C to 70°C). Electrical performance is fully interchangeable.

Q: What is the difference between these substitute parts?

A: The primary differences are packaging format and product status. The SN74AS760NSR is supplied in Tape & Reel (TR) format with Active product status. The SN74AS760NS is supplied in Tube format with Last Time Buy status. The SN74AS760NSE4 is also supplied in Tube format with Last Time Buy status. All mechanical and electrical parameters remain identical.

Q: Can I use the SN74AS760NSR in place of the SN74AS760NSE4 on existing PCBs?

A: Yes. The SN74AS760NSR is housed in the same 20-SOIC package with identical pin configuration and mechanical dimensions (0.209" width, 5.30mm). Direct substitution on existing printed circuit boards is supported without design modifications.

Q: What does Last Time Buy product status mean?

A: Last Time Buy indicates that the manufacturer has discontinued production and will no longer accept new orders after a specified date. Existing inventory is available, but supply is limited. The SN74AS760NSE4 and SN74AS760NS carry this status. The SN74AS760NSR, with Active status, continues in production and offers extended availability.

Q: Are all three parts RoHS compliant?

A: Yes. The SN74AS760NSE4, SN74AS760NSR, and SN74AS760NS are all ROHS3 compliant. All parts maintain Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture handling requirements during storage or assembly.

Q: Which substitute should I select for a new design?

A: The SN74AS760NSR is the appropriate choice for new designs. Its Active product status ensures continued availability and manufacturing support. Tape & Reel packaging is standard for automated assembly processes in production environments.

Q: Can I mix packaging formats in the same assembly?

A: Packaging format selection depends on assembly process requirements. Tape & Reel (TR) format is optimized for automated pick-and-place equipment. Tube format is suitable for manual assembly or processes configured for tube-packaged components. Electrical and mechanical compatibility is maintained across all packaging formats.
