Overview
The SN74ALS09DR is a quadruple 2-input positive-AND gate from the Texas Instruments ALS logic series. It operates within a supply voltage range of 4.5 V to 5.5 V and features an SOIC-14 surface-mount package. Key electrical parameters include a low-level output current of 8 mA, a high-level output current of 100 uA, and a propagation delay of 54 ns. The device supports a minimum operating temperature of 0°C and a maximum of +70°C.
Feature Summary
- Contains four independent 2-input AND gates for complex logic implementation
- Provides enhanced speed-performance-to-power product characteristics typical of the Advanced Low-Power Schottky series
- Designed for standard TTL input levels with defined output drive capabilities
Applications
- Digital logic circuit design requiring multiple AND functions
- Data processing systems utilizing standard logic families
- Industrial control applications compatible with specified voltage ranges
Procurement Notes
Verify the specific ordering suffix against official manufacturer documentation to confirm package type and reel specifications. Ensure the component meets RoHS requirements as stated in the datasheet. Confirm availability status directly with authorized distributors, as production lifecycles may affect stock levels. Cross-reference the manufacturer part number with ECAD models for accurate footprint integration.
Selection Notes
Select this component when designing circuits that require multiple AND gates with moderate speed and low power consumption. The ALS series offers a balance between performance and power dissipation suitable for general-purpose digital applications. Verify that the system voltage remains within the 4.5 V to 5.5 V range and that thermal conditions stay within the specified operating temperature limits.
Part Context
This part belongs to the SN74ALS family, which represents Advanced Low-Power Schottky technology. This series improves upon standard 74LS performance by offering faster switching speeds while maintaining lower power consumption. The SN74ALS09 specifically provides quad 2-input AND functionality, serving as a fundamental building block for combinational logic designs in electronic systems.
Replacement Considerations
Compatible substitutes include SN74ALS09N for through-hole mounting or SN74ALS09ANSR for tape-and-reel packaging. Verify pin compatibility and electrical specifications before substitution.
