  1. Hi all,
    I got a little confused with the data selector.
    im looking for a data selector to select 8 bit of data comming from a micro controller port going to one of two led driver IC ULN2803.
    i plan to use 2 of quadruple 1 to 2 data selector.
    this means 1 bit from microcontroller can go to the input of one the driver IC.
    i've search the net, but all i found is data selector that select 2 input to 1 output.
    this is the oopsite type of fuction that i need.
    My question are :
    1. what is the part number for the IC that i need?
    2. can i use 2 input to 1 output data selector as a 1 input to 2 output data selector?

    best regards

  2. Hi all, i'm a newbie.
    can any body please share me some information about demultiplxer IC.
    im looking for a 4 to 16 bit demultiplexer IC with active high output.
    normally i use DM74LS154N which gives active low output.

    I also looking for an 8 bit led driver IC to drive 200 mA current.
    or a darlington transistor array (8 or 16 transistor each single chips)

    i have try to find it on www.alldatasheet.com but no luck.

    can any body help me please?

    thank you :)
