Overview
The SN74ALS09NSR is a quadruple 2-input positive-AND gate from the Texas Instruments ALS logic series, housed in a 14-pin SOIC package. It operates within a supply voltage range of 4.5 V to 5.5 V and supports a low-level output current of 8 mA with a high-level output current of 100 uA. The device exhibits a propagation delay of 54 ns and functions reliably across an operating temperature range of 0°C to +70°C.
Feature Summary
- Contains four independent 2-input AND gates for complex logic implementation
- Features open-collector outputs suitable for wired-AND configurations
- Provides TTL-compatible input levels for broad system integration
Applications
- Digital logic circuit design requiring multiple AND operations
- Bus arbitration systems utilizing wired-AND logic structures
- Interface circuits connecting TTL-compatible components
Procurement Notes
Verify the specific suffix 'NSR' against the manufacturer's official documentation to confirm the SOIC-14 package type and reel packaging specifications. Ensure the component meets RoHS compliance requirements as indicated in the datasheet before final procurement decisions are made.
Selection Notes
Select this component when open-collector outputs are required for wired-AND applications or level shifting. The ALS series offers improved speed over standard TTL while maintaining lower power consumption than AS variants. Confirm that the 54 ns propagation delay aligns with the target system timing constraints.
Part Context
This part belongs to the SN74ALS09 family of quad 2-input AND gates with open-collector outputs. It is distinct from the SN74ALS08, which features standard totem-pole outputs rather than open-collector configurations. Both share similar electrical characteristics but differ significantly in output drive capabilities and application suitability.
Replacement Considerations
The SN74ALS08N serves as a functional substitute if open-collector outputs are not required. Verify pin compatibility and ensure the replacement maintains the necessary voltage and current ratings for the specific application environment.
