    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.

    5-to-32 decoder

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

    5*32 decoder

    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

    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

    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.
