74F11SC AND Gate IC Equivalent & Substitute Parts

Part Overview

The 74F11SC is a 3-channel AND gate logic IC manufactured by onsemi in 14-SOIC surface mount packaging. This component implements three independent 3-input AND gates in a single 14-pin package. The part is currently listed as obsolete, making identification of active equivalent and substitute parts essential for ongoing design support and procurement.

Substitute Part Grouping Explanation

Substitution of the 74F11SC is determined by strict equivalence across the following parameters: logic type (AND gate), number of circuits (3), number of inputs (3), supply voltage range (4.5V ~ 5.5V), output current specifications (1mA high, 20mA low), input logic levels (0.8V low, 2V high), propagation delay (5.6ns @ 5V, 50pF), and operating temperature range (0°C ~ 70°C).

The substitute parts are grouped into three categories based on packaging and product status:

Direct Manufacturer Equivalent (SN74F11DR): Identical electrical specifications and 14-SOIC package footprint. Active product status with RoHS3 compliance.

Similar Manufacturer Part (SN74F11NSR): Identical electrical specifications with 14-SO package (0.209" width vs. 0.154" width). Active product status with RoHS3 compliance. Package width difference requires PCB layout verification.

Parametric Equivalent (SN74F11D): Identical electrical specifications and 14-SOIC package footprint. Last Time Buy product status with RoHS3 compliance.

Engineering Selection Recommendations

SN74F11DR (Texas Instruments) is the primary substitute for the obsolete 74F11SC. This part maintains identical electrical specifications, package footprint (14-SOIC 0.154" width), and mounting type. Active product status ensures long-term availability. RoHS3 compliance satisfies environmental regulatory requirements. Tape & Reel packaging supports automated assembly processes.

SN74F11D (Texas Instruments) provides parametric equivalence with identical electrical specifications and package footprint. Last Time Buy status indicates limited future availability; procurement should prioritize SN74F11DR for new designs or long-term production requirements.

SN74F11NSR (Texas Instruments) offers electrical equivalence but with a wider 14-SO package (0.209" vs. 0.154"). This part is suitable only when PCB layout accommodates the increased package width. Active product status supports availability. Selection of this part requires explicit PCB design verification.

Frequently Asked Questions (FAQ)

Q: Can SN74F11DR directly replace 74F11SC without PCB modifications? A: Yes. SN74F11DR maintains identical electrical specifications and 14-SOIC package footprint (0.154" width). No PCB layout changes are required for direct substitution.

Q: What is the difference between SN74F11DR and SN74F11NSR? A: Both parts have identical electrical specifications and logic function. The difference is package width: SN74F11DR uses 14-SOIC (0.154"), while SN74F11NSR uses 14-SO (0.209"). PCB footprint compatibility must be verified before selecting SN74F11NSR.

Q: Why is SN74F11D listed as Last Time Buy? A: Last Time Buy status indicates the manufacturer has announced end-of-life for this part. Existing inventory may be available, but future procurement is not guaranteed. For new designs, SN74F11DR (Active status) is recommended.

Q: Are all substitute parts RoHS3 compliant? A: Yes. SN74F11DR, SN74F11NSR, and SN74F11D are all RoHS3 compliant. The original 74F11SC does not list RoHS status.

Q: What packaging formats are available for these substitutes? A: SN74F11DR is supplied in Tape & Reel (TR) format for automated assembly. SN74F11D is supplied in Tube format. SN74F11NSR is supplied in Tape & Reel format. Packaging selection depends on assembly process requirements.

Q: Do all parts have the same moisture sensitivity level? A: Yes. All parts, including the original 74F11SC, have MSL Rating 1 (Unlimited), indicating no moisture sensitivity restrictions.
