What is a select line?

What is a select line?

A select line selects something, like a specific chip. A control line is a line that controls something. A select line is a form of control line, along with such things as read, write, etc.

What is select line in digital electronics?

select lines, which are used to select which input line to send to the output. A multiplexer makes it possible for several input signals to share one device or resource, for example, one analog-to-digital converter or one communications transmission medium, instead of having one device per input signal.

How many select lines will be there if the inputs of a MUX are 8?

3
An 8 × 1 multiplexer selects one of the 8 inputs and presents it to the output, i.e. So the number of select lines will be 3.

How do you select a whole line?

Select an entire line of text by holding down the “Shift” key and pressing “End”, if you are at the beginning of the line, or “Home” if you are at the end of the line. Select an entire paragraph by placing your cursor at either the beginning or the end of that paragraph.

How many lines will a 64 to 1 multiplexer have?

Hence, total number of 4 : 1 MUX are required to implement 64 : 1 MUX = 16 + 4 + 1 = 21.

How many select lines does a 4 1 multiplexer require?

A 4-to-1 multiplexer consists four data input lines as D0 to D3, two select lines as S0 and S1 and a single output line Y. The select lines S0 and S1 select one of the four input lines to connect the output line.

What does the dashed line mean on a control circuit?

The dashed line indicates that when one component is changed the other one is changed, at the same time. The double-acting push buttons illustrated in number 5 will both operate when one of them is pushed. 2. Field wired or installed components. 3. Components used only in special circumstances. 4. Factory wired or installed components.

What is the name of the chip select line?

Chip select ( CS) or slave select ( SS) is the name of a control line in digital electronics used to select one (or a set) of integrated circuits (commonly called “chips”) out of several connected to the same computer bus, usually utilizing the three-state logic. One bus that uses the chip/slave select is the Serial Peripheral Interface Bus

How many data select lines do you need for multiplexer?

So for a 4-input multiplexer we would therefore require two data select lines as 4-inputs represents 22 data control lines give a circuit with four inputs, I0, I1, I2, I3 and two data select lines A and B as shown.

How are multiplexers used in digital logic circuit?

Multiplexers in Digital Logic. It is a combinational circuit which have many data inputs and single output depending on control or select inputs. For N input lines, log n (base2) selection lines, or we can say that for 2 n input lines, n selection lines are required. Multiplexers are also known as “Data n selector, parallel to serial convertor,
