Key Features
- 4-bit magnitude comparison with A>B, A=B, and A<B outputs for complete digital sorting and ordering logic
- Cascadable architecture allows direct expansion to 8-bit, 16-bit, or wider comparisons without additional logic gates
- CMOS 4000-series technology provides wide supply voltage operation and low static power consumption suitable for battery-powered designs
Applications
The CD4063BME4 is used in digital sorting circuits, priority encoders, and address decoders where numeric magnitude comparison of binary values is required. It is commonly applied in process control systems and industrial equipment to compare sensor readings or setpoints against threshold values. The cascadable feature makes it well suited for building wider word-length comparators in PLCs, embedded controllers, and custom logic boards.

Frequently Asked Questions
What comparison outputs does the CD4063BME4 provide?
The CD4063BME4 provides three output signals: A greater than B, A equal to B, and A less than B. These true-polarity outputs allow direct use in sorting, priority, and conditional branching logic without additional inversion circuitry.
How do you cascade multiple CD4063BME4 devices for wider bit comparisons?
The CD4063BME4 has cascading input pins that accept the A>B, A=B, and A<B outputs from a lower-order stage. By connecting the outputs of the less-significant comparator to the cascade inputs of the more-significant comparator, designers can build 8-bit, 12-bit, or wider comparators using multiple devices.
What is the load capacitance specification of the CD4063BME4?
The CD4063BME4 is rated for a load capacitance of 50 pF per output, which is consistent with standard 4000-series CMOS fanout requirements and typical PCB trace capacitances in low-to-medium speed logic applications.
What package does the CD4063BME4 use?
The CD4063BME4 is housed in a 16-pin SOIC (Small Outline Integrated Circuit) package, referenced as JESD-30 code R-PDSO-G16. This surface-mount package is suitable for automated PCB assembly and occupies minimal board space.
Is the CD4063BME4 compatible with TTL logic levels?
As a CMOS 4000-series device, the CD4063BME4 operates over a wide supply range and is level-compatible with TTL when powered from 5 V, though interfacing at other supply voltages may require level-shifting, as its input thresholds scale with VDD.
