Gates or IC to use to convert 1x 4 bit 2x 4 bit

In summary, a binary to BCD decoder, such as the 74185 chip, can be used to separate 2 binary digits from a 4 or 5 bit binary input and display them using 2 BCD-7 segment decoder/drivers. Other options include using a microcontroller or programmable logic chip, using 5 LEDs and learning to read binary, or using a BCD-7seg decoder/driver with defined output for input a-f.

example 1111 = 15 is there a circuit to separate output binaries 0001(1) and 0101(5) in input 1111(15)?

A binary to BCD decoder does what you want. There were the 74LS/HC/HCT185 ICs, but it might be difficult to get one today.

my question was to separate 2 binary digits out of the 4 or 5 bit binary. to display it using 2x 7 segment

Binary Coded Decimal (BCD) is the same as binary for 0-9, but then it carries to 10 and not to 0A. So this is exactly what you want. A single 74185 chip will decode up to 6 bits of binary to 2 digits of BCD.
(You have to add one or two BCD-7segment decoder/drivers)

Of course you could use a microcontroller or a programmable logic chip, as discussed http://www.electronics-related.com/usenet/basics/show/29703-1.php.

Other alternatives:
- simply use 5 Leds and learn to read binary
- use a BCD-7seg decoder/driver with defined output for input a-f and learn to read this (74247, iirc)
- two digit octal display with two standard BCD-7seg decoder/drivers
 

FAQ: Gates or IC to use to convert 1x 4 bit 2x 4 bit

1. What is the difference between a gate and an integrated circuit (IC)?

A gate refers to a basic logic circuit that performs a specific function, such as AND, OR, or NOT. An integrated circuit (IC) is a complex electronic circuit that contains multiple gates and other components on a single chip.

2. Which one is more suitable for converting 1x 4 bit to 2x 4 bit?

It depends on the specific application and requirements. In general, an IC would be more suitable as it can perform multiple functions and is more compact than using individual gates. However, if the conversion is simple and only requires one or two gates, using a gate might be more cost-effective.

3. How do gates and ICs convert from 1x 4 bit to 2x 4 bit?

Gates and ICs use basic logic operations, such as AND, OR, and NOT, to manipulate the input signals and produce the desired output. In the case of converting from 1x 4 bit to 2x 4 bit, the gates or ICs would perform logical operations on the 4 bits of input data to generate 8 bits of output data.

4. What are the advantages of using an IC over individual gates?

Using an IC can save space and reduce the complexity of the circuit. It also allows for more functions to be performed on a single chip, which can make it more efficient and cost-effective. Additionally, ICs are often more reliable and have better performance compared to individual gates.

5. How do I choose the right gate or IC for my conversion needs?

The choice of gate or IC depends on the specific requirements of the conversion, such as the number of inputs and outputs, speed, and power consumption. It is important to carefully consider these factors and select a gate or IC that meets the necessary criteria for your application.
