SN74ALS02AD

Overview

The SN74ALS02AD is a quadruple 2-input positive-NOR gate manufactured by Texas Instruments. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an operating temperature range of 0°C to +70°C. The device features a propagation delay of 12 ns, with a low-level output current of 8 mA and a high-level output current of -400 uA. It is housed in a 14-pin SOIC package.

Feature Summary

• Contains four independent 2-input NOR logic gates
• Utilizes Advanced Low-power Schottky (ALS) technology for optimized performance
• Provides standard TTL-compatible input and output characteristics

Applications

• General-purpose digital logic processing
• Signal gating and switching circuits
• Data routing applications

Procurement Notes

Verify the specific suffix 'AD' corresponds to the tube packaging format rather than tape-and-reel variants. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the selected component matches the required lead-free specifications for your manufacturing process.

Selection Notes

Select this component when four independent NOR functions are required in a single surface-mount package. Consider the ALS series for improved speed compared to standard LS logic while maintaining lower power consumption. Verify that the 14-pin SOIC footprint aligns with the target PCB layout constraints.

Part Context

This part belongs to the SN74ALS02A family of quad 2-input NOR gates. It shares functional compatibility with other industry-standard NOR gate ICs but offers distinct electrical characteristics defined by the Advanced Low-power Schottky process. The 'D' suffix indicates the SOIC-14 package type.

Replacement Considerations

Compatible substitutes include the SN74LS02AD for standard LS logic or the SN74AS02D for AS series performance. Verify pinout compatibility and electrical parameter alignment before substituting.
