HCF4585BEY

Comparators Overview

The HCF4585BEY is a 4-bit magnitude comparator manufactured by STMicroelectronics, housed in a 16-DIP package. It operates within a voltage range of 3V to 20V and supports an operating temperature range from -55°C to 125°C. The device features active high outputs indicating A<B, A=B, and A>B relationships. Key electrical specifications include a maximum quiescent current of 100 µA and a propagation delay of 160ns at 15V with a 50pF load.

Comparators Feature Summary

• Provides simultaneous comparison results for two 4-bit binary words through dedicated output pins.

Comparators Applications

• Digital logic circuits requiring magnitude comparison functions

Comparators Procurement Notes

Verify component authenticity as the HCF4585BEY is listed as obsolete by the manufacturer. Confirm package integrity and pin compatibility before integration into legacy systems. Ensure supply chain sources provide valid traceability documentation for this discontinued part number.

Comparators Selection Notes

Select this component only when a 4-bit CMOS magnitude comparator with DIP-16 packaging is required. Consider the wide operating temperature range and low quiescent current for industrial applications. Evaluate alternative modern equivalents if new designs are being developed due to obsolete status.
