What is the use of IC 74151?

What is the use of IC 74151?

The TTL/MSI SN54/74LS151 is a high speed 8-input Digital Multiplexer. It provides, in one package, the ability to select one bit of data from up to eight sources. The LS151 can be used as a universal function generator to generate any logic function of four variables.

What is the output of IC 74151?

IC 74151 is a popular 8-to-1 multiplexer IC with eight inputs and two outputs. The two outputs are active low and active high outputs. It has three select lines A, B and C and one active low enable input.

What is the function of strobe pin in 74151 IC?

A Strobe input is provided which, when at high level, disables all data inputs and forces Y output to low state and W output to high state.

What is a multiplexer IC?

A Multiplexer IC allows you to interface a number of pins, with a single pin, by using a set of state pins to determine which ones are connected. e.g. you could have 8 LEDs as Outputs, all controlled from a single output. You could also have 8 different switches as Inputs, which are all interfaced to a single input.

What is 74151 IC?

74151 IC is a high-speed digital multiplexer with 8 input. The IC provides the ability to select one bit of data from up to 8-bit data sources in a single IC package.

How do you use 74151 multiplexer?

MULTIPLEXER CIRCUIT USING IC 74151….

  1. Make the connections as per the logic diagram.
  2. Switch ON the power supply.
  3. Apply the combinations of input one by one according it the truth table.
  4. Note its Corresponding output reading.
  5. Switch OFF the power Supply.
  6. Disconnect the components.

What is a 2 4 decoder?

A 2-to-4 Binary Decoders The 2 binary inputs labelled A and B are decoded into one of 4 outputs, hence the description of 2-to-4 binary decoder. Each output represents one of the miniterms of the 2 input variables, (each output = a miniterm).

How does a mux work?

A multiplexer is a system of multiple inputs and just one output to receive signals coming from multiple acquisition networks. The device transfers all input signals to a microprocessor, which receives and processes the data, transmits it to the output devices, and controls the system as a whole.

What is IC 74139?

74139 is a high speed dual 2-to-4 line decoder IC. The IC is designed with Schottky-clamp circuits to use in high-performance memory-decoding and data-routing applications, requiring a very short propagation delay time. The active-low enable input can be used as a data line in demultiplexing applications.

How do muxes work?

What is IC strobe?

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 can a 74151 8 input multiplexer IC do?

74151 IC is a high-speed digital multiplexer with 8 input. The IC provides the ability to select one bit of data from up to 8-bit data sources in a single IC package. This IC can work as a universal function generator for generating any logic function of four variables. You must be logged in to post a review.

How does strobe I / P work in IC 74151a?

Normally strobe (G) input is incorporated which is generally active low which enables the multiplexer when it is LOW. Strobe i/p helps in cascading. IC 74151A is an 8: 1 multiplexer which provides two complementary outputs Y & Y. The o/p Y is same as the selected i/p & Y is its complement.

How is a multiplexer used in a Data Selector?

The multiplexer is a data selector which gates one out of several inputs to a single o/p. It has n data inputs & one o/p line & m select lines where 2m= n shown in fig a.

What kind of circuit is a multiplexer circuit?

Multiplexer is a combinational circuit that is one of the most widely used in digital design. The multiplexer is a data selector which gates one out of several inputs to a single o/p.
