SN74F11D Equivalent & Substitute Parts

Part Overview

The SN74F11D is a 3-channel AND gate logic IC manufactured by Texas Instruments in 14-SOIC surface mount packaging. This device implements three independent 3-input AND gates in a single integrated circuit package. The SN74F11D is currently in Last Time Buy status, indicating end-of-life production. Identifying equivalent and substitute parts is necessary to ensure design continuity and maintain supply chain reliability for applications requiring this logic function.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SN74F11D is determined by strict equivalence across the following critical parameters:

• Logic function: 3-channel AND gate with 3 inputs per channel
• Electrical specifications: 4.5V to 5.5V supply voltage, 1mA/20mA output current, 0.8V/2V input logic levels, 5.6ns maximum propagation delay
• Package type: 14-SOIC surface mount form factor with 0.154" width (3.90mm)
• Base product number: 74F11 series

The SN74F11DR qualifies as a direct substitute based on identical electrical and functional parameters. The primary difference is packaging format: the SN74F11D is supplied in Tube packaging, while the SN74F11DR is supplied in Tape & Reel (TR) format. Both devices are manufactured by Texas Instruments and meet the same electrical and mechanical specifications required for direct substitution.

Parameter Comparison

Engineering Selection Recommendations

The SN74F11DR is a direct functional and electrical equivalent to the SN74F11D. Both devices are manufactured by Texas Instruments and comply with ROHS3 and REACH requirements. The SN74F11D is designated Last Time Buy status, indicating discontinued production. The SN74F11DR maintains Active product status with higher inventory availability (3700 pcs vs. 1770 pcs).

Selection between these parts should be based on supply chain requirements and packaging format compatibility. The SN74F11DR in Tape & Reel format is suitable for automated assembly processes, while the SN74F11D in Tube format may be preferred for manual assembly or lower-volume applications. Both parts meet identical electrical specifications and are pin-compatible within the 14-SOIC package footprint.

Frequently Asked Questions (FAQ)

Q: Can the SN74F11DR directly replace the SN74F11D in existing designs?

A: Yes. The SN74F11DR is electrically and functionally identical to the SN74F11D. Both devices implement three 3-input AND gates with identical electrical characteristics, operating ranges, and timing specifications. Pin configuration and package footprint are identical.

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

A: Tube packaging supplies components in plastic tubes suitable for manual handling and lower-volume assembly. Tape & Reel (TR) packaging supplies components on continuous tape wound on reels, optimized for automated pick-and-place assembly equipment. Both formats contain the same die and offer identical electrical performance.

Q: Why is the SN74F11D marked as Last Time Buy?

A: Last Time Buy status indicates that Texas Instruments has discontinued production of this part number. Existing inventory may be available for a limited time. The SN74F11DR remains in Active production status and is the recommended long-term alternative.

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

A: No. Both the SN74F11D and SN74F11DR are ROHS3 compliant, REACH unaffected, and carry identical moisture sensitivity levels (MSL 1 - Unlimited). Compliance certifications are equivalent.

Q: What are the critical parameters for substitution?

A: Substitution is valid when the following parameters match: logic type (AND gate), number of circuits (3), number of inputs per circuit (3), supply voltage range (4.5V to 5.5V), output current specifications (1mA/20mA), input logic levels (0.8V/2V), propagation delay (5.6ns @ 5V, 50pF), operating temperature range (0°C to 70°C), and package type (14-SOIC surface mount).
