SN74ALS08NSR

Overview

The SN74ALS08NSR is a quadruple 2-input positive-AND gate from the Texas Instruments 74ALS 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. The device provides a low-level output current of 8 mA and a high-level output current of -400 uA. It is housed in a 14-SOIC surface-mount package and supports an operating temperature range from 0°C to +70°C.

Feature Summary

• Contains four independent 2-input AND logic gates for parallel signal processing
• Utilizes Advanced Low-power Schottky (ALS) technology for optimized speed and power consumption
• Provides robust low-level sink current capability for driving standard TTL loads

Applications

• Digital logic circuit design requiring multiple AND operations
• Data acquisition systems for input signal gating
• Industrial control logic interfaces

Procurement Notes

Verify the specific suffix 'SR' indicates tape-and-reel packaging configuration distinct from tube or cut-tape variants. Confirm RoHS compliance status through official manufacturer documentation as regulatory requirements may vary by production batch. Ensure the SOIC-14 package dimensions match the target PCB footprint constraints before finalizing procurement orders.

Selection Notes

Select this component when designing circuits that require moderate switching speeds with lower power dissipation than standard 74S series devices. The ALS family offers a favorable balance between propagation delay and static power consumption. Verify that the 4.5 V minimum supply voltage aligns with the system's available power rails and that the 14 ns delay meets the timing requirements of the application.

Part Context

This part belongs to the Texas Instruments 74ALS08 family, which consists of quadruple 2-input AND gates. The SN74ALS08NSR specifically denotes the surface-mount version in a 14-pin Small Outline Integrated Circuit (SOIC) package. It is part of the broader 74xx series logic ecosystem, providing compatibility with other standard logic families while offering improved performance characteristics over legacy designs.

Replacement Considerations

SN74ALS08DR: Alternative surface-mount variant in SOIC-14 package. SN74ALS08N: Through-hole PDIP-14 equivalent. SN74ALS08NE4: Lead-free compliant version of the PDIP package.
