Overview
The SN74AHCT08NS is a quadruple 2-input positive-AND gate manufactured by Texas Instruments. It belongs to the 74AHCT logic series, utilizing CMOS technology with HCT-compatible inputs for direct interface with TTL-driven systems. The device operates within a supply voltage range of 4.5 V to 5.5 V and features low static power consumption. It provides four independent AND gates in a single package, offering high-speed performance suitable for digital logic applications requiring reliable signal processing.
Feature Summary
- Integrates four independent 2-input AND logic functions within a single integrated circuit package.
- Features HCT-compatible input thresholds allowing direct interfacing with standard TTL logic systems.
- Utilizes advanced CMOS technology to achieve high switching speeds while maintaining low static power dissipation.
- Designed for robust operation across extended industrial temperature ranges.
Applications
- Digital signal processing circuits requiring logical conjunction operations
- Interface modules connecting TTL-based systems with CMOS logic components
- Control logic networks in embedded systems and microcontroller peripherals
Procurement Notes
Verify the specific suffix 'NS' against the manufacturer's current datasheet to confirm pinout compatibility and package dimensions. Ensure the component meets RoHS compliance requirements for your assembly process. Cross-reference the ordering information with official Texas Instruments documentation to validate availability and manufacturing status before finalizing procurement plans.
Selection Notes
Select this component when HCT-compatible input levels are required alongside AHCT-level speed performance. It serves as a suitable alternative to standard HC or HCT families where faster propagation delays are necessary. Consider the operating temperature range and supply voltage constraints to ensure compatibility with the target system environment and power budget.
Part Context
This part is a member of the Texas Instruments 74AHCT08 family, which combines the speed of AHCT technology with the input compatibility of HCT standards. The family includes various package options such as SOIC, TSSOP, and SSOP. The SN74AHCT08NS specifically denotes the NS package variant, providing a standardized solution for quad 2-input AND gate applications in mixed-voltage digital designs.
Replacement Considerations
Direct substitutes include other SN74AHCT08 variants with different package suffixes (e.g., PWR, DBR) if pinout compatibility allows. Generic equivalents from other manufacturers may require verification of input threshold voltages and output drive capabilities to ensure functional parity.
