Can you design 5 bit comparator using IC 7485?
Every 7485 IC has three cascading input lines which can used in this case because we are using only one IC to make 7485 comparator. So, as shown in above diagram. Now we have 5 bits inputs. Input side is done!
How does IC 7485 work?
The 4-bit comparator is mostly available in IC form and common type of this IC is 7485. This IC can be used to compare two 4-bit binary words by grounding I (A>B), I (A
What is the use of cascading inputs in comparator?
“What is the purpose of the cascading inputs of IC 7485?” When you’re cascading multiple devices, and the inputs are identical, the result depends on the other devices processing the least significant bits. The output of the comparator processing lower order bits have to be connected to the cascading inputs.
What is the use of Cascade inputs?
Cascading input controls in a report reduce a large number of choices to a manageable number. A single value chosen for a cascading input control determines which other values appear as choices for input. For example, the choice of a country determines which states or regions are listed as choices.
What is 8bit comparator?
An 8-bit comparator compares the two 8-bit numbers by cascading of two 4-bit comparators. The circuit connection of this comparator is shown below in which the lower order comparator AB outputs are connected to the respective cascade inputs of the higher-order comparator.
How does a 4-bit comparator work?
4-Bit Magnitude Comparator – A comparator used to compare two binary numbers each of four bits is called a 4-bit magnitude comparator. It consists of eight inputs each for two four bit numbers and three outputs to generate less than, equal to and greater than between two binary numbers.
What is a 7485 comparator?
IC 7485 is a four bit comparator IC. It compares two 4-bit words A(A3−A0)andB(B3–B0). It is possible to cascade mode than one IC 7485 to compare words of almost any length by making use of the cascade pins of the IC.
What are the output of a 7485 four bit magnitude comparator?
Correct Answer: Quad two-input multiplexer.
What is magnitude comparator explain 1 bit magnitude comparator?
1-Bit Magnitude Comparator – A comparator used to compare two bits is called a single bit comparator. It consists of two inputs each for two single bit numbers and three outputs to generate less than, equal to and greater than between two binary numbers.
How does magnitude comparator work?
A digital comparator or magnitude comparator is a hardware electronic device that takes two numbers as input in binary form and determines whether one number is greater than, less than or equal to the other number. Comparators are used in central processing units (CPUs) and microcontrollers (MCUs).
What is cascading inputs in magnitude comparator?
A comparator performing the comparison operation to more than four bits by cascading two or more 4-bit comparators is called cascading comparator. When two comparators are to be cascaded, the outputs of the lower-order comparator are connected to corresponding inputs of the higher-order comparator.
What is the main function of the cascade amplifier?
A cascade amplifier is a two-port network designed with amplifiers which are connected in series when every amplifier transmits its o/p to the second amplifiers input in a daisy chain. The problem in measuring the gain of the cascaded stage is the non-perfect coupling among two stages because of loading.
