Key Parameters

Substitute Part Grouping Explanation

Substitution for the SN74LV11AD is determined by strict equivalence across the following critical parameters:

• Logic Type: AND Gate with 3 channels and 3 inputs per channel
• Voltage Supply Range: 2V ~ 5.5V
• Current Specifications: Quiescent current 20 µA maximum; output drive 12mA high and low
• Input Logic Levels: Low 0.5V, High 1.5V
• Propagation Delay: 7.9ns @ 5V, 50pF
• Operating Temperature Range: -40°C ~ 85°C
• Package: 14-SOIC surface mount
• Compliance: ROHS3 Compliant, MSL Level 1

The substitute part SN74LV11ADR maintains identical electrical and functional specifications while differing only in packaging format (Tape & Reel versus Tube) and product status (Active versus Discontinued).

Parameter Comparison

Engineering Selection Recommendations

The SN74LV11ADR is the direct substitute for the SN74LV11AD. Both parts are manufactured by Texas Instruments and maintain identical electrical characteristics, logic functionality, and compliance certifications. The primary distinction is product status: the SN74LV11AD is discontinued at DiGi Electronics, while the SN74LV11ADR remains active in production.

Selection between these parts depends on procurement requirements. The SN74LV11ADR in Tape & Reel packaging is suitable for high-volume automated assembly operations. The SN74LV11AD in Tube packaging, while discontinued, may remain available through alternative distribution channels for lower-volume applications or legacy system maintenance.

Both parts satisfy ROHS3 compliance and MSL Level 1 requirements, ensuring compatibility with standard surface mount assembly processes and storage conditions.

Frequently Asked Questions (FAQ)

Q: Can the SN74LV11ADR directly replace the SN74LV11AD in existing designs?

A: Yes. The SN74LV11ADR is electrically and functionally identical to the SN74LV11AD. Both parts feature the same 14-SOIC package, pinout, logic specifications, and operating parameters. The only differences are product status and packaging format.

Q: What is the difference between Tube and Tape & Reel packaging?

A: Tube packaging contains individual components in a plastic tube, suitable for manual handling and small-quantity orders. Tape & Reel packaging presents components on a continuous tape wound on a reel, designed for automated pick-and-place assembly equipment. Both formats contain the same component.

Q: Are there any compliance or certification differences between these parts?

A: No. Both the SN74LV11AD and SN74LV11ADR carry identical ROHS3 compliance and MSL Level 1 ratings. They meet the same regulatory and environmental standards.

Q: Why is the SN74LV11AD discontinued?

A: The SN74LV11AD is discontinued at DiGi Electronics. The SN74LV11ADR remains the active production part from Texas Instruments and is the recommended choice for new designs and ongoing procurement.

Q: Can I use these parts interchangeably in my circuit board?

A: Yes. The identical 14-SOIC package, pinout, and electrical specifications ensure direct interchangeability. No circuit modifications or design changes are required.
