CD74HC85NSR

Comparators Overview

The CD74HC85NSR is a high-speed CMOS 4-bit magnitude comparator manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 6 V and features low static power dissipation. The device provides true outputs for greater than, less than, and equal conditions. It is housed in a 16-pin SOIC package with a propagation delay of approximately 30 ns at 5 V. The component supports an operating temperature range from -55°C to +125°C.

Comparators Feature Summary

• Performs 4-bit magnitude comparison between two binary words
• Provides cascading inputs for expanding comparison width
• Delivers true logic outputs for GT, LT, and EQ conditions

Comparators Applications

• Digital arithmetic logic units
• Address decoding systems
• Data sorting circuits

Comparators Procurement Notes

Verify the specific suffix NSR indicates the tape-and-reel packaging format. Confirm the manufacturer is Texas Instruments and the part number matches exactly. Check RoHS compliance status as indicated in official documentation. Ensure the SOIC-16 package dimensions align with PCB layout requirements.

Comparators Selection Notes

Select this component when a 4-bit comparator with wide voltage flexibility is required. The HC series offers compatibility with standard TTL logic levels while maintaining low power consumption. Consider the 16-pin SOIC package for surface-mount assembly needs. Verify that the propagation delay meets the system timing constraints.

Comparators Part Context

This part belongs to the CD74HCxx series of high-speed CMOS logic devices. It is functionally compatible with other 74HC family comparators but distinguished by its specific pinout and packaging. The NSR suffix denotes the reel-based packaging variant suitable for automated placement.
