## What is the function table of IC 7483?

IC 7483 is a digital adder IC that can add two 4 bit numbers. IC 7483 consists of four individual full adder circuits which are internally connected. It has also input and output carry circuit. IC 7483 can be connected directly to the CMOS, NMOS, and TTL circuits.

**What is a 7483 IC?**

IC 7483 is a 4 bit parallel adder which consists of four interconnected full adders along with the look ahead carry circuit. The pin diagram of IC 7483 is shown above. It is a 16pin IC. The IC adds the two four bit words along with input carry to prooduce a 4 bit sum and a one bit carry-out.

**Is IC 7483 is a BCD adder?**

The 4-bit binary adder IC (7483) can be used to perform addition of BCD numbers. In this, if 4- bit sum output is not a valid BCD digit, or if carry C3 is generated, then decimal 6 (0 1 1 0) is to be added to the sum to get the correct result. Following fig (0) shows 4-bit BCD Adder.

### Which IC is use for 4-bit addition?

IC 4008 is a CMOS chip that can add two 4-bit binary numbers. The result is given right away as a 5-bit number. It is called a 4-Bit Full Adder.

**What is full adder IC?**

Specifications. These full adders perform the addition of two 4-bit binary numbers. The sum outputs are provided for each bit and the resultant carry (C4) is obtained from the fourth bit. These adders feature full internal look ahead across all four bits.

**How do you make a full adder?**

Implementation of Full Adder using Half Adders 2 Half Adders and a OR gate is required to implement a Full Adder. With this logic circuit, two bits can be added together, taking a carry from the next lower order of magnitude, and sending a carry to the next higher order of magnitude.

#### What is 4bit binary adder?

The ′F283 is a full adder that performs the addition of two 4-bit binary words. The sum (Σ) outputs are provided for each bit and the resultant carry (C4) output is obtained from the fourth bit. The adder logic, including the carry, is implemented in its true form.

**What is a BCD adder?**

A 4-bit binary adder that is capable of adding two 4-bit words having a BCD (binary-coded decimal) format. The result of the addition is a BCD-format 4-bit output word, representing the decimal sum of the addend and augend, and a carry that is generated if this sum exceeds a decimal value of 9.

**What is 4bit Adder?**

The ′F283 is a full adder that performs the addition of two 4-bit binary words. The sum (Σ) outputs are provided for each bit and the resultant carry (C4) output is obtained from the fourth bit. The device features full internal look-ahead across all four bits generating the carry term C4 in typically 5.7 ns.

## What is 4-bit subtractor?

In Digital Circuits, A Binary Adder-Subtractor is one which is capable of both addition and subtraction of binary numbers in one circuit itself. The operation being performed depends upon the binary value the control signal holds. The circuit consists of 4 full adders since we are performing operation on 4-bit numbers.
