CD4585BD

Comparators Overview

The CD4585BD is a CMOS 4-bit magnitude comparator manufactured by Harris Corporation. It operates within a supply voltage range of 3 V to 18 V and supports through-hole mounting in a 16-pin DIP package. The device provides active high outputs for A < B, A = B, and A > B comparisons. Key electrical specifications include a maximum propagation delay of 250 ns at 10 V and 160 ns at 15 V with a 50 pF load. It functions reliably across an industrial temperature range from -55 °C to +125 °C.

Comparators Feature Summary

• Performs 4-bit magnitude comparison between two binary inputs
• Provides distinct active high logic outputs for less than, equal, and greater than conditions
• Supports wide supply voltage operation suitable for various digital systems

Comparators Applications

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

Comparators Procurement Notes

Verify the manufacturer origin carefully, as this component was originally produced by Harris Semiconductor, which was acquired by L3Harris Technologies. Confirm that the specific unit matches the required hermetic or plastic packaging variant, as both CDIP and PDIP options exist in the product lineage. Ensure compliance with current environmental regulations if RoHS status is critical for the assembly process.

Comparators Selection Notes

Select this component when a dedicated 4-bit magnitude comparison function is required in a through-hole design. It is suitable for applications needing wide voltage tolerance and robust performance in extreme temperatures. Consider the propagation delay characteristics relative to system clock speeds. Verify pin compatibility if replacing legacy designs originally specified for Harris Semiconductor parts.

Comparators Part Context

This part belongs to the CD4585B series of CMOS logic devices. Originally developed by Harris Semiconductor, production rights and inventory are now managed by L3Harris Technologies. The device is part of the broader 4000-series logic family, known for high noise immunity and low power consumption in static states compared to earlier TTL technologies.
