SN74ALS08NS

Overview

The SN74ALS08NS 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 a propagation delay of 14 ns at 5 V with 50 pF load capacitance. The device provides a low-level output current of 8 mA and a high-level output current of -400 µA. It is housed in a 14-pin SOIC package and supports surface-mount installation. The component functions reliably across an operating temperature range of 0°C to +70°C.

Feature Summary

• Contains four independent 2-input AND logic gates for signal processing
• Utilizes Advanced Low-power Schottky (ALS) technology for optimized performance
• Provides standardized TTL-compatible input and output voltage levels

Applications

• Digital logic circuit design requiring quad AND functionality
• Signal gating and data routing in electronic systems
• Industrial control logic interfaces

Procurement Notes

Verify the specific suffix 'NS' against official manufacturer documentation to confirm the exact package variant and tape-and-reel specifications. Ensure compatibility with standard SOIC-14 footprints during PCB layout. Confirm RoHS compliance status through the latest datasheet revision notes before finalizing procurement orders.

Selection Notes

Select this component when a balance between speed and power consumption is required compared to standard LS or S series alternatives. The ALS series offers faster switching speeds than LS devices while maintaining lower power dissipation than S series parts. Verify that the 14 ns propagation delay meets the timing requirements of the target digital application.

Part Context

This part belongs to the SN74ALS family, which represents an advancement over the earlier SN74LS series. The ALS technology improves propagation delay significantly while reducing power consumption. The SN74ALS08NS specifically integrates four AND gates into a single compact surface-mount package, serving as a fundamental building block for complex digital logic designs.

Replacement Considerations
