Overview
The SN74AS02DR is a quadruple 2-input positive-NOR gate manufactured by Texas Instruments. It belongs to the AS (Advanced Schottky) logic series and is housed in a 14-pin Small Outline Integrated Circuit (SOIC) package. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports an industrial temperature range from 0°C to +70°C. Key electrical characteristics include a maximum low-level output current of 20 mA, a high-level output current of -2 mA, and a typical propagation delay of 5.5 ns at 5 V with a 50 pF load.
Feature Summary
- Integrates four independent 2-input NOR gates within a single integrated circuit package.
- Utilizes Advanced Schottky technology to achieve high-speed switching performance.
- Features push-pull outputs capable of driving standard TTL loads.
Applications
- Digital logic signal processing
- Data acquisition systems
- Industrial control circuits
Procurement Notes
Verify that the ordering suffix DR corresponds to the SOIC-14 surface-mount package and tape-and-reel quantity. Confirm RoHS compliance status and lead times directly with authorized distributors or Texas Instruments. Ensure the component meets specific environmental requirements for the intended application environment.
Selection Notes
Select this component when high-speed NOR logic functionality is required in a compact surface-mount form factor. Compare against SN74ALS02 variants if lower power consumption is prioritized over speed. Verify pin compatibility and thermal management needs for the target PCB layout design.
Part Context
This part is part of the Texas Instruments SN74AS family, which offers faster switching speeds compared to standard 74LS logic while maintaining compatible pinouts. The 'D' suffix indicates the SOIC package type, and 'R' denotes reel packaging. It serves as a direct replacement for other 74AS02 devices in existing designs requiring surface-mount assembly.
Replacement Considerations
SN74AS02DG4 is a verified equivalent variant offering identical logical function and specifications. Cross-reference datasheets to confirm package dimensions and electrical tolerances match the original design requirements before substitution.
