IC 4063 Datasheet, Pinout Working, Applications

Last Updated on March 3, 2023 by Swagatam 2 Comments

The IC 4063 is a CMOS-based 4-bit magnitude comparator IC that can compare two 4-bit binary or BCD numbers and determine which one is greater than or equal to the other. It operates on a supply voltage range of 3V to 18V and is compatible with TTL logic levels.

IC 4063 pinout

The IC 4063 has a 16-pin dual in-line package (DIP) as shown in the above pinout diagram:

Pinout Explanation

The IC 4063 is 4-bit magnitude comparator chip which is normally used is computers and logic circuits. In these applications, the IC 4063 calculates and finds out whether or not a 4-bit word (Binary or BCD) is equal to, less than, or greater than a subsequent 4-bit word.

You will find 8 pinouts in the IC 4063 which are assigned for the comparator functions. These pinouts are A0 (pin#10), A1 (pin#12), A2 (pin#13) A3 (pin#15), B0 (pin#9), B1 (pin#11), B2 (pin#14), B3 (pin#1).

The IC 4063 also includes 3 inputs for the cascading function. These are pin#2 (A < B), pin#3 (A = B) and pin#4 (A > B).

The above 3 inputs facilitate the developers to upgrade the comparator functioning of the IC to 8, 12, 16, or up to 4N bits.

If you want to cascade the inputs of a single IC 4063, you can do it in the following manner:

  • (A < B) = Low,
  • (A = B) = High,
  • (A > B) = Low

In order to process words that are longer than 4 bits, multiple IC 4043 ICs could be cascaded by hooking up the outputs of the less significant comparator with the relevant corresponding inputs of the more significant comparator..

For example the 3 inputs (A < B) = Low, (A = B) = High, (A > B) = Low, from a least significant IC 4063 should be connected to low, high, low logic in the cascaded system.

Applications:

The IC 4063 can be used in a wide range of applications that require the comparison of two 4-bit binary or BCD numbers, such as:

  • Digital counters
  • Arithmetic circuits
  • Control systems
  • Instrumentation
  • Data acquisition systems
  • Communications systems

About Swagatam

I am an electronics engineer and doing practical hands-on work from more than 15 years now. Building real circuits, testing them and also making PCB layouts by myself. I really love doing all these things like inventing something new, designing electronics and also helping other people like hobby guys who want to make their own cool circuits at home.

And that is the main reason why I started this website homemade-circuits.com, to share different types of circuit ideas..

If you are having any kind of doubt or question related to circuits then just write down your question in the comment box below, I am like always checking, so I guarantee I will reply you for sure!

    Goodnight!
    Based on this 4063 ci, could you create a universal audio cable test with connections, xlr, trs, rca?
    Thanks in advance for your attention once again

      Hi Carlos, that looks difficult to me…but I will try to figure it out if possible, and let you know.
