What does a 74LS138 do?

74LS138 is a complex TTL based logical device used to convert 3-bit binary data to 8-bits. The actual purpose of this chip is designed for demultiplexing or in machine language we can say as a decoding device. The device takes 3 input data and converts it to 8-bit data.

How many pins are there in 74138 IC?

The Integrated Circuit is of 16 pins. We have three input pins which are actively in high state and are classified as I2, I1 and I0. The outputs are actively in low state and are eight in number and are classified as O7*, O6*, …, O0*.

What is 74LS138 decoder?

The LSTTL/MSI SN54/74LS138 is a high speed 1-of-8 Decoder/ Demultiplexer. This device is ideally suited for high speed bipolar memory chip select address decoding.

What is an IC Class 8?

The concept of fabricating an entire circuit on a single small block (or chip) of a semiconductor has revolutionised electronics technology. Such a circuit is known as Integrated Circuit (IC).

What is IC 74139?

BD 1.300. 74LS138 is a member from '74xx'family of TTL logic gates. The chip is designed for decoding or de-multiplexing applications and comes with 3 inputs to 8 output setup.

Which IC is used for decoder?

3 to 8 line decoder IC 74HC238 is used as a decoder/ demultiplexer. 3 to 8 line decoder demultiplexer is a combinational circuit that can be used as both a decoder and a demultiplexer. IC 74HC238 decodes three binary address inputs (A0, A1, A2) into eight outputs (Y0 to Y7). The device also has three Enable pins.

What is the IC number of the 2x4 decoder?

IC 74LS155 DUAL 2-to-4 LINE DECODER/DEMULTIPLEXER.

Why are decoder used?

The decoder is an electronic device that is used to convert a digital signal to an analog signal. It allows a single input line and produces multiple output lines. The decoders are used in many communication projects that are used to communicate between two devices.

What is the function of pin 3 on the 7447?

Pin number 3 is display test (lamp test) function which is active low. When pin number 3 input is low, irrespective of other input pin signals, all the segment outputs a,b,c,d,e,f & g are low & all segments of the display will glow.

How many pins are there in IC 7483?

The pin diagram of IC 7483 is shown above. It is a 16pin IC. The inputs to the IC are A, B and Cin0 while outputs are S and Cout3. A3A2A1A0 is a 4 bit input word 'A' and B3B2B1B0 is the second 4 bit input word 'B'.

How many multiplexers are there in IC 74153?

The 74153 MUX has two separate 2-input/4-row MUXs on it. To create a single 16-row truth table, we can start by implementing parts of the table on different MUXs, and then combining the two separate outputs into one output.

What is a 4-bit binary decoder?

A 4-to-16 binary decoder has 4 inputs and 8 outputs. It can easily be created by combining two 3-to-8 decoders together and can be used to convert any 4-bit binary number (0 to 15) into “hexadecimal” using the following truth table.

What are the types of decoder?

Decoder

2 to 4 line decoder: In the 2 to 4 line decoder, there is a total of three inputs, i.e., A₀, and A₁ and E and four outputs, i.e., Y₀, Y₁, Y₂, and Y₃.
3 to 8 line decoder: The 3 to 8 line decoder is also known as Binary to Octal Decoder. ...
4 to 16 line Decoder.

What is a 3 bit decoder?

A 3-bit decoder has 3 input lines and 8 output lines. That is, 8 decoding gates are required to decode all possible combinations of three bits. For any given code on its input, one of the eight output becomes HIGH. Advertisements. Binary codes corresponding outputs and decoding functions are described in the table.

What are IC types?
