SN74LS682DWRG4

Overview

The SN74LS682DWRG4 is an 8-bit magnitude and identity comparator manufactured by Texas Instruments. It operates within a supply voltage range of 4.85 V to 5.25 V and features active low outputs. The device exhibits a propagation delay time of 30 ns and has a maximum supply current of 70 mA. It is housed in a SOIC-20 package and supports an operating temperature range from 0°C to +70°C.

Feature Summary

• Performs 8-bit magnitude and identity comparisons
• Provides active low output signals for comparison results

Applications

• Digital data comparison circuits
• Address decoding systems
• Error detection logic

Procurement Notes

Verify the specific suffix G4 indicates RoHS compliance and green manufacturing status as per Texas Instruments documentation. Confirm the SOIC-20 package dimensions match your PCB footprint requirements. Ensure the operating environment stays within the specified 0°C to +70°C temperature range for reliable performance.

Selection Notes

Select this component when 8-bit comparison functionality with LS logic speed is required. Consider the 4.85 V to 5.25 V supply constraint. Evaluate the SOIC-20 package for surface mount assembly compatibility. Compare against HC or HCT variants if wider voltage ranges or different speeds are needed.

Part Context

This part belongs to the Texas Instruments SN74LS series, which utilizes Low-power Schottky technology. The SN74LS682 specifically functions as an 8-bit comparator. The DWRG4 designation identifies the SOIC-20 package variant with lead-free and halogen-free attributes.

Replacement Considerations

SN74HC682DWR offers similar functionality with a wider voltage range and lower power consumption. SN74ALS682 provides faster switching speeds but may require different power management.
