How many 3-to-8 line decoders with an enable input are needed to construct a 6-64?
You need 9 3-to-8 decoders. 8 decoders for selecting one of 64 lines. 1 decoder for enabling 1 decoder out of 8 decoder.
How many 2-input and gates can replace n-input and gate Does that apply for nand gates as well?
for a two input gate to represent as an n-input gate excatly n-1 two input gates are required. this implies that for a two input OR gate to represent a four input OR gate exactly three two input OR gates are required let F is =a+b+c+d =(((a+b)+c)+d) =((a+b)+(c+d)) in both the above cases + is used three times so three two input OR gates make a four input OR gates. This discussion doesnot hold good for NAND gates an example can illlustrate the reson:- take F=(a.b.c.d)'=a'+b'+c'+d' --------------------------->(1) (this is obtained by a four input NAND gate) let us take this in the manner we did it for an OR gate and we will then verify the result. =((a.b)'(c.d)')' =((a'+b').(c'+d'))' =(a'+b')'+(c'+d')' =ab+cd <------------------------(2) (1)is not equal to (2) so we can say that a NAND gate cannot be replaced in the manner as OR gate is replaced
Design and draw a combinational circuit using AND-OR-NOT gates that accepts 4 input bits and produces two bit output the first of the two bits is set to 1 if the number of 1s in the input is even?
Design and draw a combinational circuit using AND-OR-NOT gates that accepts 4 input bits, and produces two bit output; the first of the two bits is set to 1 if the number of 1's in the input is even; and the second of the output bit is set to 1 if the input have 3 or more (all four) 1 bits.
What is ic 74150?
It is a data selector. There are 16 digital input lines, 4-bit decoder, strobe and output pin. So you put a 4-bit binary number from 0-15 into ABCD bits and the corresponding input value is found on output at the strobe time.
How do you use an amplifier?
Amplifiers comes in IC packages diagram is triangle with +/- input by adding a resistor r1 in series to the - input the gain can be found by adding a resistor from output to the - input The + terminal must be satisfied with the proper resistor
Draw the logic diagram of 2 to 4 line decorder with only nor gates include an enable input?

How many 3-to-8 line decoders with an enable input are needed to construct a 6-64?
You need 9 3-to-8 decoders. 8 decoders for selecting one of 64 lines. 1 decoder for enabling 1 decoder out of 8 decoder.
How does demux differ than decoder?
the basic difference is that there is 1 input line for the demux whereas a decoder has no input lines
How do you make 4 to 1 multiplexer using 4 three-state buffer and decoder?
connect S1 and S0 to a 2x4 active high decoder then connect each output of the decoder with the enable of each three-state buffer. Each of with has an input of D0,D1,D2,D3 respectively. Connect the outputs of each with an OR gate (since only one can be active at a time, whichever's active will be the output).
What is the number of inputs and outputs of a decoder that accepts 64 input combinations?
1
How do you enable the text-box in html?
You can enable the text box in HTML using input tag. The input tag asks the input type and make it to Text.
What is the flag input of AND gate?
To produce a 3-input OR gate when only 2-input OR gates are available: Use 3 OR gates Inputs to Gate A are input 1 and input 2 Input to Gate B is input 3 (if 2 inputs are necessary, include input...
Block diagram of ic-7489 as 16x4 ram?
Use the link below to go to the data sheet for the IC. On page 5-4 you will see the logic diagram. Using it you can see that A0 - A3 are the address lines used to select the memory location to read from or write to. There are 16 locations. These work in conjunction with the 4 input AND IC's 1-16. These are the decoder section to decode the address and select the memory row. Pin 2 is the Memory Enable pin. This pin enables the memory when it is held low. At the bottom of the page you see the 4 data inputs D1-D4. These are used to input data into memory when the Write Enable Pin (Pin 3) is held low. When the Write enable pin is held high, the data stored at the memory location selected by the address lines will be placed on the outputs. However, the outputs are complemented. So if the data at the selected address is 1001, the output will be 0110. Thus to see the actual data, you would need an inverter on the outputs. So you basically have the address decoder, the memory cells, and the I/O control if you want it in blocks.
What is the pin diagram of Integrated Chip L293D?

What are the basic building blocks of digital ICs?
Usually NAND gates or NOR gates, as these are the universal gates from which all other gates, flipflops, registers, etc. can be built. - - - - - There are four basic building blocks: gates with more than one input: AND: output high if all inputs high OR: output high if any input high gates with one input: buffers: output high if input high; these are used at the ends of long wiring runs so following gates get clear signals--IOW, they're amplifiers inverters: output low if input high A NAND gate is an AND with an inverter follower, and a NOR is an OR with an inverter follower.
Write the program with flowchart do not cheat?
You have start diagram follow by input diagram and output diagram, then exit diagram.
