What are the key features of CD4063BEE4?
- 4-bit magnitude comparator with cascadable expansion inputs supports chaining to 8-bit or wider word comparison using multiple devices
- CD4000 CMOS family operates from 3 V to 15 V supply, tolerating wide supply swings in battery-powered and industrial environments
- Three simultaneous comparison outputs (A>B, A=B, A<B) provide complete relational information with 4 mA output sink for direct LED or logic-level drive
What is CD4063BEE4 used for?
The CD4063BEE4 is used in set-point comparators, address decoders, and range-detection circuits in industrial PLCs and analog front-end boards where a hardware comparison of 4-bit BCD or binary values must be made without microprocessor intervention. Its 3 V to 15 V supply range accommodates both 5 V TTL-compatible and 12 V industrial control bus systems, making it versatile for legacy board redesigns. The through-hole DIP-16 package simplifies installation in breadboards and socketed prototyping environments.

Frequently Asked Questions
What supply voltage range does the CD4063BEE4 support, and does it operate on 12 V industrial control rails?
The CD4063BEE4 operates from 3 V to 15 V, covering both the 5 V TTL-compatible range and 12 V industrial control bus voltages, making it one of the few 4-bit comparators directly usable in older PLC backplane environments without a separate level translator or supply regulator.
How are multiple CD4063BEE4 devices cascaded to compare bytes or nibbles wider than 4 bits?
The three cascade inputs (IA>B, IA=B, IA<B) accept the comparison result from a lower-order CD4063BEE4 stage; connecting two stages handles 8-bit comparisons, three stages handle 12-bit, and so on, with the most-significant stage's outputs (A>B, A=B, A<B) giving the final result of the full word comparison.
What propagation delay should be expected from the CD4063BEE4 when operating at 5 V, and does it meet the timing budgets of typical 4000-series logic designs?
At 5 V with a 50 pF load, the CD4063BEE4 has a typical propagation delay of approximately 200 ns to 400 ns, which is consistent with the broader CD4000 CMOS family and comfortably fits static combinational comparison applications where speed is not the primary constraint.
Can the CD4063BEE4 replace a 74HC85 in an existing 5 V design, and are there timing trade-offs?
The CD4063BEE4 is functionally pin-compatible with the 74HC85 and 74LS85 in the 16-pin DIP footprint, but its 4000-series CMOS propagation delay at 5 V (approximately 200 ns) is about 15 times slower than the HC85 (approximately 13 ns), so it is best used in non-time-critical comparisons or when the wider supply range (up to 15 V) is the deciding requirement.
Is the CD4063BEE4 suitable for through-hole prototyping and educational lab use?
Yes. The 16-pin DIP package fits standard breadboards and IC sockets with 0.3-inch row spacing, and the device's 3 V to 15 V supply tolerance means it works from a 9 V battery or regulated 5 V bench supply equally well, making it a popular teaching component for digital logic labs demonstrating magnitude comparison and cascading principles.
