What are the key features of CD4585BE?
- 4-bit magnitude comparator with cascading inputs enabling expansion to 8-bit, 12-bit, or wider word comparisons without external glue logic
- Three output flags (A>B, A=B, A<B) providing complete comparison results in a single IC for arithmetic and sorting logic
- CMOS 4000-series family device supporting wide supply voltage operation from 3 V to 15 V for legacy and mixed-voltage systems
What is CD4585BE used for?
The CD4585BE is used in digital sorting and ranking circuits, process control comparators, and address decode logic where two 4-bit values must be compared and their magnitude relationship acted upon. Its cascadable architecture allows multiple units to be chained in series to handle 8-bit or 16-bit comparison tasks in ALU designs, industrial threshold detectors, and programmable logic control systems operating across 3 V to 15 V supply rails.

Frequently Asked Questions
How many bits can the CD4585BE compare in a single device, and how is it expanded to wider word widths?
The CD4585BE compares two 4-bit binary words, producing A>B, A=B, and A<B outputs. For 8-bit comparisons, two CD4585BE devices are cascaded by connecting the output flags of the lower-nibble stage to the cascading inputs of the upper-nibble stage, requiring no additional logic gates.
What output signals does the CD4585BE produce, and how are they used in a digital control system?
The device produces 3 outputs: A greater than B, A equal to B, and A less than B. In a temperature or pressure control system, these 3 flags directly drive setpoint alarm relays or interrupt lines without requiring a microcontroller to decode the comparison result, reducing system latency to the propagation delay of the CD4585BE, typically under 100 ns at 5 V.
What supply voltage range does the CD4585BE support, and what load capacitance is it rated for?
As a CD4000-series CMOS device, the CD4585BE operates from 3 V to 15 V supply. Each output is rated for 50 pF load capacitance, which is compatible with standard CMOS and TTL inputs on PCB trace lengths up to 20 cm in typical 5 V and 12 V logic systems.
For an 8-bit address comparator in an embedded memory map decoder, how many CD4585BE devices are needed and how are they connected?
Two CD4585BE devices are sufficient for an 8-bit comparison. The first compares the lower 4 bits (A[3:0] vs B[3:0]) with cascading inputs tied to the equal condition, and its 3 output flags feed the cascading inputs of the second device that compares the upper 4 bits (A[7:4] vs B[7:4]). The final A=B output from the second device asserts only when all 8 bits match.
