SN74ALS08NSRG4

Overview

The SN74ALS08NSRG4 is a quadruple 2-input positive-AND gate manufactured by Texas Instruments. It belongs to the 74ALS logic series and is housed in a 14-SOIC surface-mount package. The device operates within a supply voltage range of 4.5 V to 5.5 V. Key electrical parameters include a propagation delay of 14 ns, a low-level output current of 8 mA, and a high-level output current of -400 uA. It supports a commercial operating temperature range from 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 robust low-level sink current capability for driving loads

Applications

• Digital logic circuit design requiring multiple AND functions
• Data acquisition systems utilizing standard TTL-compatible logic levels
• Industrial control applications within specified temperature ranges

Procurement Notes

Verify the specific ordering suffix 'G4' against the manufacturer's latest documentation to confirm compliance with RoHS directives and material composition requirements. Ensure the SOIC-14 package dimensions match the target PCB footprint. Confirm that the 4.5V to 5.5V supply voltage aligns with the system power architecture before finalizing procurement.

Selection Notes

Select this component when a balance between speed and power consumption is required compared to standard LS logic. The ALS series offers faster switching speeds than LS devices while consuming less power than AS series parts. Verify that the 14-SOIC package is suitable for the assembly process and that the 8 mA output drive strength meets the load requirements of the connected circuitry.

Part Context

This part is a lead-free, halogen-free variant of the SN74ALS08NSR. The 'G4' suffix indicates compliance with environmental standards. It is part of the broader 74ALS family, which bridges the performance gap between older LS logic and newer high-speed CMOS technologies. It serves as a drop-in replacement for legacy designs requiring improved speed without excessive power draw.

Replacement Considerations

Direct pin-compatible alternatives include the SN74ALS08DR and SN74ALS08N. For automotive applications, consider the SN74AHC08QDRG4Q1 or SN74LV08ATPWRG4Q1, which offer wider voltage ranges and extended temperature capabilities.
