74F11SCX AND Gate IC Equivalent & Substitute Parts

Part Overview

The 74F11SCX is a 3-channel AND gate logic IC manufactured by onsemi in a 14-SOIC surface mount package. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement. The 74F11 series provides standard TTL-compatible AND gate functionality suitable for digital logic applications requiring three independent 3-input AND gates in a single package.

Substitute Part Grouping Explanation

Substitution eligibility for the 74F11SCX is determined by matching the following critical parameters: logic type (AND gate), circuit count (3 channels), input count (3 inputs per gate), supply voltage range (4.5V ~ 5.5V), output current specifications (1mA high, 20mA low), input logic thresholds (0.8V low, 2V high), propagation delay (5.6ns @ 5V, 50pF), operating temperature range (0°C ~ 70°C), and package compatibility (14-SOIC surface mount).

The substitute parts are categorized as follows:

Direct Manufacturer Equivalent (SN74F11D): Identical electrical and mechanical specifications with matching 14-SOIC package footprint. Differs only in packaging format (tube vs. unspecified for main part) and product status (Last Time Buy).

Similar Equivalent (SN74F11NSR): Matches all electrical parameters and core functionality. Package variant uses 14-SO with slightly different width specification (0.209", 5.30mm vs. 0.154", 3.90mm), requiring PCB layout verification. Supplied in Tape & Reel format with Active product status.

Parametric Equivalent (SN74F11DR): Fully compatible electrical and functional specifications with identical 14-SOIC package footprint. Supplied in Tape & Reel format with Active product status.

Engineering Selection Recommendations

For Direct Pin-Compatible Replacement: SN74F11DR is the preferred choice. It maintains identical electrical specifications, package footprint (14-SOIC 0.154" width), and offers Active product status with ROHS3 compliance. This part requires no PCB layout modifications and provides the longest supply availability.

For Last-Time-Buy Scenarios: SN74F11D provides direct equivalence with matching package dimensions but carries Last Time Buy status, indicating limited future availability. Selection of this part should be accompanied by transition planning to SN74F11DR.

For Tape & Reel Packaging Requirements: Both SN74F11NSR and SN74F11DR are supplied in Tape & Reel format. SN74F11NSR requires PCB layout verification due to package width variance (0.209" vs. 0.154"). SN74F11DR maintains identical package dimensions and is recommended for this application.

All substitute parts comply with REACH and EAR99 export classifications matching the original component.

Frequently Asked Questions (FAQ)

Q: Can SN74F11NSR be used as a direct replacement for 74F11SCX?

A: SN74F11NSR is electrically equivalent but has a package width specification of 0.209" (5.30mm) compared to the original 0.154" (3.90mm). PCB footprint compatibility must be verified before substitution. If the PCB is designed for the narrower 0.154" package, SN74F11DR is the appropriate choice.

Q: What is the difference between SN74F11D and SN74F11DR?

A: Both parts are electrically and mechanically identical with matching 14-SOIC package specifications. The primary difference is packaging format: SN74F11D is supplied in tube packaging, while SN74F11DR is supplied in Tape & Reel format. SN74F11DR also maintains Active product status versus Last Time Buy for SN74F11D.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. SN74F11D, SN74F11NSR, and SN74F11DR are all ROHS3 compliant. The original 74F11SCX is REACH Unaffected. All parts share identical HTSUS and ECCN classifications.

Q: What is the moisture sensitivity level for these parts?

A: All parts, including the original 74F11SCX and all substitutes, have Moisture Sensitivity Level (MSL) 1, indicating unlimited shelf life without moisture control requirements.

Q: Why is the 74F11SCX listed as obsolete?

A: The 74F11SCX is an onsemi product that has reached end-of-life status. Texas Instruments continues to manufacture functionally equivalent parts (SN74F11D, SN74F11NSR, SN74F11DR) with Active or Last Time Buy status, ensuring design continuity.
