MC14585BFELG

Comparators Overview

The MC14585BFELG is a 4-bit magnitude comparator integrated circuit manufactured by onsemi. It operates within a supply voltage range of 3V to 18V and features active-high outputs indicating A<B, A=B, or A>B conditions. The device utilizes TTL-compatible output stages with specified high and low output currents of 4.2mA each. It is housed in a 16-pin SOEIAJ package with dimensions of 0.209 inches (5.30mm) width. The component supports an operating temperature range from -55°C to +125°C and exhibits a maximum propagation delay of 260ns at 15V with 50pF load.

Comparators Feature Summary

• Performs magnitude comparison between two 4-bit binary words
• Provides distinct active-high logic outputs for less than, equal, and greater than relationships
• Compatible with standard TTL logic families for interface simplicity

Comparators Applications

• Digital arithmetic logic units requiring magnitude determination
• Control systems utilizing binary word comparison
• Data processing circuits needing relational status signals

Comparators Procurement Notes

Verify the specific suffix BFELG against official manufacturer documentation to confirm the tape-and-reel packaging format and exact pinout configuration. Confirm RoHS compliance status and REACH declaration details through current datasheets. Check product change notices for any manufacturing site transitions or material updates that may affect compatibility.

Comparators Selection Notes

Select this component when a 4-bit magnitude comparison function is required with TTL-compatible output levels. Ensure the design accommodates the specified 3V to 18V supply range and the thermal requirements for operation up to 125°C. Consider the 16-pin SOEIAJ footprint constraints during PCB layout planning.
