MC14585BDG

Comparators Overview

The MC14585BDG is a 4-bit magnitude comparator from the onsemi 4000B CMOS logic series. It operates within a supply voltage range of 3V to 18V and features TTL-compatible outputs with high-active signaling for A<B, A=B, and A>B conditions. The device is housed in a 16-pin SOIC package measuring 10 x 4 x 1.5mm. It supports an operating temperature range from -55°C to +125°C. Key electrical parameters include a static current of 20 µA, output currents of 4.2mA (high/low), and a maximum propagation delay of 260ns at 15V with 50pF load.

Comparators Feature Summary

• Provides simultaneous digital comparison results indicating less than, equal to, or greater than relationships between two 4-bit binary inputs.
• Features TTL-compatible outputs to facilitate direct interfacing with standard logic families without additional level shifting.
• Operates across a wide industrial temperature range suitable for demanding environmental conditions.

Comparators Applications

• Digital arithmetic logic units requiring magnitude determination
• Address decoding systems in embedded controllers
• Error detection circuits comparing data values

Comparators Procurement Notes

Verify component authenticity through authorized distributors as this part is listed as obsolete by the manufacturer. Confirm RoHS compliance status and check for available surplus stock from certified suppliers. Ensure the 16-SOIC package dimensions match your PCB footprint requirements before finalizing procurement decisions.

Comparators Selection Notes

Select this component when a 4-bit comparison function with TTL-compatible outputs is required. Consider the 4000B series compatibility if integrating with other legacy CMOS logic devices. Evaluate the wide operating temperature range against your specific environmental constraints and verify power supply stability within the 3V to 18V specification.
