5 to 32 decoder

Dear,
I want to construct a 5-to-32 line decoder with four 3-ro-8 line decoders with enable and a 2-to-4 line decoder.
 

5 32 decoder

you have 5 input lines and you need output lines

now let lines are
d0 lsb
d1
d2
d3
d4 msb

connect d3 and d4 to 2-to-4 line decoder
connect d0, d1, and d2 to all 3-to-8 line decoders.

Now connect output of 2-to-4 line decoder to enable pins of 3-to-8 line decoders such that the first output makes first 3-to-8 line decoders enable.

thats it 32 output of 3-to-8 line decoders are your required output

again try your self and if u need schematic just post in here.
don't forget to press help me button if this was helpful.

my friend if we don't put any inverters is it still right?

nikhilele, your circuit will not work! ABC lines of bottom 3 ICs are not connected! and last IC has no connection at all !

Here is the corrected schematic. You can also use inverter (7404) instead of AND gate with last IC. In that case connect D3 to G1 and inverted D4 to G2A.

EDIT: Ohh I didn't notice this thread is almost 3 year old!! anyways :D
 
1 of 32 decoder

Sir, how will I extend this to make a 10 to 1024 decoder? will using 4 to 16 decoders be feasible?

I would suggest use a CPLD or FPGA for it rather than discrete ICs
 

6-to-64 line decoder

hi cmos! how about a 6 to 64 decoder?? thanks!

Its doable. You'll need 16 of them. But I haven't seen any discrete 6 to 64 decoder IC!

This is how you implement it. Quite easy, isn't it? :D
 
line decoder

yeah thanks buddy, i was implementing it through using 2-4 and 3-8 decoders.
i will be needing ur help again if u cud help me in designin 5-32 bit decoder in NOR logic.

Thats what I have done.

Here is the implementation using NOR gates.

32 line decoder

1st of all thank u, u r rite but i was deployin 4 3-8 decodern n 1 2-4 deocder.
i wanted to ask again if the ip lines 4m 3-8 decoder at the end of above box r to connected elsewhere also? same in 2nd box?
 

3 to 8 line decoder

No they are just the inputs. Not connected anywhere else. E is MSB, A is LSB.
Since its matrix connection, you only need one 3-8 and one 2-4 decoder.

Please do not use SMS/Text type language here (ip = input, 4m = from). Its hard to read it.
 

decoder5*32




My project is CMOS 6T SRAM Implementation in different technology for SNM ,DRV,RM & WM Analysis.

Frist i have to do READ & WRITE operation means i want to do calculate of Cell Ratio & PULL-UP Ratio. Then I want to do analysis of SNM ,DRV ,WM & RM .So please send me reponse as soon as possible that How will i do this project & also Circuit diagram.I am confused in input & Output of this circuit.plz response me.
