How many bits is IC 7485?

IC 7485 is a four bit comparator IC.

How do you create a 4-bit magnitude comparator?

A comparator used to compare two binary numbers each of four bits is called a 4-bit magnitude comparator….4-Bit Magnitude Comparator –

1. If A3 = 1 and B3 = 0.
2. If A3 = B3 and A2 = 1 and B2 = 0.
3. If A3 = B3, A2 = B2 and A1 = 1 and B1 = 0.
4. If A3 = B3, A2 = B2, A1 = B1 and A0 = 1 and B0 = 0.

## Is a 4-bit magnitude comparator IC?

The other two outputs are also use Ex-NOR outputs to generate the Boolean functions as shown figure. 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 comparator IC?

A comparator is an electronic circuit, which compares the two inputs that are applied to it and produces an output. The output value of the comparator indicates which of the inputs is greater or lesser. Please note that comparator falls under non-linear applications of ICs.

What is the use of cascade counter input in IC 7485?

The cascading inputs come from the outputs of another 7485. If you wish to create a 16 bit magnitude comparator, the other 7485 connects to the least significant byte (LSB).

Which is very widely used and popular combinational unit?

One of the most common uses of combinational logic is in Multiplexer and De-multiplexer type circuits. Here, multiple inputs or outputs are connected to a common signal line and logic gates are used to decode an address to select a single data input or output switch.

## What is a 4-bit comparator IC?

General Description. These 4-bit magnitude comparators perform comparison of straight binary or BCD codes. Three fully-decoded deci- sions about two, 4-bit words (A, B) are made and are exter- nally available at three outputs. These devices are fully expandable to any number of bits without external gates.

### What is 4-bit number?

A 4-bit unsigned binary number system. A 4-bit unsigned binary number has values ranging from 00002 (010) to 11112 (1510). Hence, it is a modulo-100002, or modulo-1610. Modern computers typically support binary integers of 8, 16, 32, or 64 bits.

What is IC LM358?

The LM358 IC is a great, low power and easy to use dual channel op-amp IC. It is designed and introduced by national semiconductor. It consists of two internally frequency compensated, high gain, independent op-amps. This IC is designed for specially to operate from a single power supply over a wide range of voltages.
