CD74HC85NS

Comparators Overview

The CD74HC85NS is a high-speed CMOS logic component manufactured by Texas Instruments, functioning as a 4-bit magnitude comparator. It operates within a supply voltage range of 2.0V to 6.0V and features buffered inputs and outputs for signal integrity. The device provides active high outputs to indicate the relationship between two 4-bit binary numbers. It is housed in a 16-pin Small Outline Package (SOP) designed for surface mount technology applications.

Comparators Feature Summary

• Performs 4-bit magnitude comparison with active high outputs
• Features buffered inputs and outputs for improved signal handling
• Operates on high-speed CMOS logic technology

Comparators Applications

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

Comparators Procurement Notes

Verify the package type matches the required 16-pin SOP configuration. Confirm the manufacturer is Texas Instruments to ensure compatibility with specified logic levels. Check RoHS compliance status if environmental regulations apply to the assembly process. Ensure the operating temperature range meets the specific application requirements.

Comparators Selection Notes

Select this component when a 4-bit magnitude comparison function is required in a digital circuit. Consider the 2.0V to 6.0V supply voltage range for compatibility with various logic families. The buffered I/O characteristics make it suitable for driving multiple loads or long traces in PCB layouts.

Comparators Part Context

This part belongs to the CDx4HC85 family of high-speed CMOS logic devices. It is specifically designed for magnitude comparison tasks in digital electronics. The NS suffix indicates the 16-pin SOP package variant, distinguishing it from other packaging options like TSSOP or DIP.

Comparators Replacement Considerations

Compatible substitutes include the CD74HC85MRE and CD74HC85NSR. Verify pinout compatibility and electrical specifications before substitution.
