SN74F11NSR

Overview

The SN74F11NSR is a high-speed silicon-gate CMOS logic device from the Texas Instruments SN74F series. It contains three independent 3-input AND gates housed in a 14-pin SOIC surface-mount package. The component operates within a supply voltage range of 4.5 V to 5.5 V and supports a propagation delay of 10 ns at 5 V with a 50 pF load. It features TTL-compatible input levels and provides standard output drive capabilities suitable for digital logic applications.

Feature Summary

• Integrates three independent 3-input AND logic functions within a single integrated circuit
• Utilizes high-speed silicon-gate CMOS technology for efficient operation
• Provides TTL-compatible input thresholds for direct interfacing with TTL logic systems

Applications

• Digital logic circuits requiring multiple AND operations
• Data processing systems utilizing 5V logic families
• Industrial control logic interfaces

Procurement Notes

Verify the specific suffix 'NSR' corresponds to the SOIC-14 package and tape-and-reel packaging configuration. Confirm RoHS compliance status through official manufacturer documentation, as environmental declarations may vary by production batch. Ensure the operating temperature range meets system requirements before finalizing procurement decisions.

Selection Notes

Select this component when three separate 3-input AND gates are required in a compact surface-mount form factor. The SN74F series offers faster switching speeds compared to standard 74LS equivalents but consumes higher static power. Verify that the 5V supply voltage and TTL input compatibility align with the target system architecture.

Part Context

This part belongs to the SN74F family of high-speed CMOS logic devices manufactured by Texas Instruments. The F series represents an evolution in speed over earlier LS technologies while maintaining pinout compatibility with standard 7400-series logic functions. The SN74F11 specifically implements the triple 3-input AND gate function common in complex digital designs.

Replacement Considerations

Equivalent parts include the SN74F11N (DIP package) or SN74F11SC (SOIC without reel). Cross-reference with other manufacturers offering SN74F11 variants, ensuring package dimensions and electrical characteristics match the original design specifications.
