Overview
The SN74ALS09NS is a quadruple 2-input positive-AND gate from the Texas Instruments SN74ALS series. It operates within a supply voltage range of 4.5 V to 5.5 V and features an SOIC-14 surface-mount package. The device provides a low-level output current of 8 mA and a high-level output current of -400 uA. Propagation delay is specified at 14 ns, with an operating temperature range from 0°C to +70°C.
Feature Summary
- Contains four independent 2-input AND logic gates in a single integrated circuit
- Utilizes Advanced Low-power Schottky (ALS) technology for optimized speed and power consumption
- Designed for standard 5V digital logic systems with defined TTL input/output compatibility
Applications
- Digital logic signal processing circuits
- Data path gating and control logic
- General-purpose boolean logic implementation
Procurement Notes
Verify the specific suffix 'NS' against the manufacturer's official datasheet to confirm the exact package type and tape-and-reel specifications. Ensure the component meets RoHS compliance requirements for your target application. Cross-reference the ordering part number with authorized distributors to confirm availability and authenticity before procurement.
Selection Notes
Select this component when four independent 2-input AND functions are required in a compact surface-mount form factor. The ALS series offers a balance of switching speed and power dissipation suitable for general digital applications. Verify that the 8 mA sink current capability meets the load requirements of the connected downstream logic inputs.
Part Context
This component belongs to the SN74ALS family of high-speed logic devices manufactured by Texas Instruments. The family is characterized by improved performance over standard 74LS logic while maintaining pinout compatibility. The SN74ALS09 specifically implements AND functionality, distinguishing it from NAND or OR variants within the same series.
Replacement Considerations
Compatible substitutes include the SN74ALS09DR and SN74ALS08NSR, provided the functional logic matches the design requirements. Verify pinout compatibility and electrical characteristics such as propagation delay and output drive strength before substitution.
