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
