74AC11002D

Overview

The Texas Instruments 74AC11002D is a quadruple 2-input positive-NOR gate integrated circuit belonging to the AC logic series. It operates within a supply voltage range of 3 V to 5.5 V and supports low-level output currents of 24 mA and high-level output currents of -24 mA. The device features a propagation delay of 5 ns and functions reliably across an operating temperature range from -40°C to +85°C. Packaged in a 16-pin SOIC-Narrow (SOP) format, it provides four independent NOR gates with two inputs each for digital signal processing applications.

Feature Summary

• Provides four independent 2-input positive-NOR logic gates within a single package
• Operates on standard 3 V to 5.5 V power supplies compatible with CMOS technology
• Delivers fast switching performance with a typical propagation delay of 5 ns
• Supports robust drive capabilities with 24 mA output current sourcing and sinking

Applications

• Digital logic circuits requiring NOR functionality
• Data acquisition systems
• Telecommunications equipment
• Portable battery-operated devices

Procurement Notes

Verify the specific suffix 'D' indicates the SOIC-16 package variant when ordering. Confirm RoHS compliance status as availability may vary by production batch. Check for end-of-life notifications or obsolescence warnings from Texas Instruments prior to finalizing procurement plans. Ensure the supplier provides valid traceability documentation for quality assurance purposes.

Selection Notes

Select this component when designing circuits that require multiple NOR gates in a compact surface-mount footprint. Compare propagation delays against system timing requirements to ensure the 5 ns speed is sufficient. Verify that the 3 V to 5.5 V operating range matches the target power supply rails. Consider the 24 mA drive strength for load driving capabilities compared to lower-current logic families.

Part Context

This part belongs to the Texas Instruments SN74ACxx series of advanced CMOS logic devices. The AC series offers higher speeds than standard 74HC devices while maintaining similar pinouts. The 74AC11002 specifically implements NOR logic, distinguishing it from NAND or AND variants in the same family. It is designed for general-purpose digital applications requiring reliable logic operations.

Replacement Considerations

Direct substitutes include other 74AC11002 variants such as the 74AC11002DR (tape and reel packaging). Cross-reference with 74ACT11002 if TTL-compatible input levels are required instead of CMOS levels. Verify package compatibility when substituting with DIP or TSSOP versions.
