Substitute Part Grouping Explanation

The SN74ALS11ANSR qualifies as a direct substitute for the SN74ALS11ANS based on the following criteria:

Matching Parameters:

• Logic type: AND Gate (3 channel, 3 input)
• Supply voltage range: 4.5V ~ 5.5V
• Output current specifications: 400µA, 8mA
• Propagation delay: 13ns @ 5V, 50pF
• Operating temperature range: 0°C ~ 70°C
• Package type: 14-SOIC (0.209", 5.30mm Width)
• Surface mount configuration
• RoHS3 compliance
• MSL rating: 1 (Unlimited)

Differentiating Factor: The primary distinction is packaging format: SN74ALS11ANS is supplied in Tube packaging (Last Time Buy status), while SN74ALS11ANSR is supplied in Tape & Reel format with Active product status and higher inventory availability.

Parameter Comparison

Engineering Selection Recommendations

The SN74ALS11ANSR is the appropriate selection for new designs and replenishment orders. This part maintains Active product status with Texas Instruments, ensuring long-term availability and supply chain stability. Both parts meet ROHS3 compliance and carry identical electrical and thermal specifications, confirming functional equivalence.

The SN74ALS11ANS remains suitable for existing inventory use or applications with immediate component requirements, provided Last Time Buy constraints are acknowledged. The Tape & Reel packaging of the SN74ALS11ANSR aligns with automated assembly processes and high-volume production workflows.

Frequently Asked Questions (FAQ)

Q: Can SN74ALS11ANSR replace SN74ALS11ANS in existing designs?

A: Yes. Both parts are electrically and mechanically identical. The 14-SOIC package dimensions, pin configuration, and electrical characteristics are equivalent. The primary difference is packaging format and product lifecycle status.

Q: What is the significance of Last Time Buy status for SN74ALS11ANS?

A: Last Time Buy indicates the manufacturer has discontinued production. Existing inventory is available but will not be replenished. For long-term supply assurance, transition to SN74ALS11ANSR is recommended.

Q: Are there packaging compatibility considerations between Tube and Tape & Reel formats?

A: Both formats contain identical components in 14-SOIC packages. Tube packaging is suitable for manual handling and small-quantity applications. Tape & Reel format is optimized for automated pick-and-place assembly. Component functionality is unchanged.

Q: Do both parts meet current compliance standards?

A: Yes. Both SN74ALS11ANS and SN74ALS11ANSR are ROHS3 compliant with MSL rating 1 (Unlimited moisture sensitivity level). Both are REACH unaffected and carry EAR99 export classification.

Q: What are the critical electrical parameters for substitution verification?

A: Supply voltage (4.5V ~ 5.5V), output current (400µA high, 8mA low), propagation delay (13ns @ 5V, 50pF), and operating temperature range (0°C ~ 70°C) must match. Both parts meet these specifications identically.
