    Hello,

    They are 8 bit counters with output registers.
    See thedatashetts for more details.

    The exact parts are available at Mouser, unless you are really desiring to have alternatives.

    Mouser does not stock the 74LS591.

    They do have the 74LS592:

    You may be able to use the 74LS590 instead of the 74LS591; the main difference is that the 591 has open-collector outputs, whereas the 590 has totem pole outputs.

    However, we do not know where you are located since you have not placed that information in your profile.
    If you are in India, you might try Farnell India, who's website is here:

    They do carry versions of the 74LS590 and 592; no 591 though.
