SN74HC682DWR

Comparators Overview

The SN74HC682DWR is an 8-bit magnitude comparator from the Texas Instruments SN74HC series. It operates within a supply voltage range of 2 V to 6 V and features low-active outputs indicating equality (A=B) or greater-than (A>B) conditions. The device utilizes a 20-SOIC package and supports surface-mount installation. It exhibits a maximum propagation delay of 47 ns at 6 V with a 50 pF load. The component functions reliably across an operating temperature range of -40°C to +85°C.

Comparators Feature Summary

• Performs 8-bit magnitude comparison between two binary inputs
• Provides dedicated low-active logic outputs for equality and greater-than status
• Compatible with standard CMOS input and output levels

Comparators Applications

• Digital data path monitoring
• Address decoding systems
• Comparator-based control logic

Comparators Procurement Notes

Verify the specific ordering suffix 'DWR' confirms the tape-and-reel packaging format and SOIC-20 physical dimensions. Ensure the design accommodates the specified 2 V to 6 V supply voltage constraints. Confirm that the 47 ns propagation delay meets the timing requirements of the target application under the intended load conditions.

Comparators Selection Notes

Select this component when an 8-bit magnitude comparison function is required in a CMOS logic environment. The HC series offers broad voltage compatibility compared to HCT variants. Consider the 20-SOIC footprint for PCB layout constraints. Verify that the low-active output polarity aligns with the downstream logic gate requirements without additional inversion stages.

Comparators Part Context

This part belongs to the SN74HC682 family of 8-bit magnitude comparators manufactured by Texas Instruments. The 'DWR' suffix denotes the specific SOIC-20 package variant supplied in a reel format. It is distinct from register or transceiver devices within the broader 74HC product line, serving specifically as a digital comparator for arithmetic decision-making circuits.

Comparators Replacement Considerations

SN74HC682DW is the equivalent non-reel version of the same comparator. SN74HCT682 provides TTL-compatible input thresholds but requires a 4.5 V to 5.5 V supply range. Cross-reference pinouts and electrical characteristics before substitution.
