Overview
The SN74AHCT02NS is a quad two-input NOR gate from the Texas Instruments SN74AHCT series, housed in a 14-pin SOIC package. It operates within a voltage range of 4.5 V to 5.5 V and features TTL-compatible inputs with low power consumption, drawing a maximum ICC of 10 μA. The device provides ±8 mA output drive capability at 5 V, ensuring robust signal integrity for digital logic applications requiring high-speed performance and noise immunity.
Feature Summary
- TTL-voltage compatible inputs ensure seamless integration with legacy logic families
- Low power consumption design minimizes energy usage during operation
- Robust ±8 mA output drive capability supports direct interfacing with loads
Applications
- Electrical tools
- Sewing machines
- DVD players
- VCD players
Procurement Notes
Verify the specific suffix 'NS' corresponds to the 14-pin SOIC package variant when sourcing. Confirm that the operating voltage requirements align with the 4.5 V to 5.5 V specification. Ensure compatibility with TTL input levels if interfacing with older digital systems. Check for RoHS compliance status as indicated in official documentation.
Selection Notes
Select this component for designs requiring quad NOR functionality with TTL input compatibility. It is suitable for applications needing low static power consumption and moderate speed. Consider the SOIC package for surface-mount assembly needs. Evaluate thermal management requirements based on the specified operating temperature range.
Part Context
This part belongs to the SN74AHCT family, which combines the high-speed performance of AHCT technology with CMOS low power characteristics. The AHCT series is designed to be pin-out and function compatible with standard HCT devices while offering improved switching speeds and lower power dissipation compared to earlier generations.
Replacement Considerations
Direct replacements include other SN74AHCT02 variants with different packaging options such as SN74AHCT02N (PDIP) or SN74AHCT02DR (SOIC). Verify that substitute parts maintain the same logic function, voltage range, and input/output specifications to ensure circuit compatibility.
