What is the function of strobe in multiplexer?

Pin 9 (STROBE) is an input signal that disables or enables the multiplexer. With high STROBE the value of A B C D doesn’t matter, the output will allways be high.

What is the use of strobe or enable input?

Explanation: The enable input is also known as strobe which is used to cascade two or more multiplexer ICs to construct a multiplexer with a larger number of inputs.

What is strobe function?

In computer or memory technology, a strobe is a signal that is sent that validates data or other signals on adjacent parallel lines. In memory technology, the CAS (column address strobe) and RAS ( row address strobe ) signals are used to tell a dynamic RAM that an address is a column or row address.

What is the use of strobe in combinational circuit?

Depending on the digital code applied at the selected inputs, one out of n data sources is selected and transmitted to the single output Y. E is called the strobe or enable input which is useful for the cascading. It is generally an active low terminal that means it will perform the required operation when it is low.

What is enable pin in multiplexer?

Multiplexer circuits typically have an enable input (EN pin in Fig. 1) in addition to the other inputs. The EN pin functions as a global on/off switch. When EN is HIGH you can use the select pins to route one of the input pins (Y0–Y3) to the output pin Y.

What is the role of select lines in multiplexer?

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.

What is the number of select line required in a single input and output demultiplexer?

of select lines. Therefore, for 1:4 demultiplexer, 2 select lines are required. Explanation: A demultiplexer sends a single input to multiple outputs, depending on the select lines.

What is strobe pin function?

The strobe pin can perform two functions: 1. Taking the output low until ready to measure the data. If the strobe pin goes low, the output is pulled low. Floating the strobe pin will give normal operation.

What is a strobe pin?

e.g., In 8-bit shift register CD4094 ,strobe pin is used as storage register clock pin. Pin 1 is the STROBE input. This input must be placed HIGH to transfer bits to the storage register. If this pin is LOW, no data can be transferred to the storage register so they won’t appear at the output.

What is the relationship between input lines and select lines?

What is the function of a multiplexer select input?

A multiplexer performs the function of selecting the input on any one of ‘n’ input lines and feeding this input to one output line. Multiplexers are used as one method of reducing the number of integrated circuit packages required by a particular circuit design. This in turn reduces the cost of the system.
