for that application you might consider using a digital comparator which gives you the freedom of freely choosing the reset number. Check out the 74HC688 as a cascadeable 8bit device. If it is a fixed number you are after, you can use smaller (N)AND gates for the lines which are meant to be 1 and (N)OR gates for the lines which are meant to be 0 for reset.
You'll find datasheet for almost all logic chips at the manufacturers' homepages, e.g.: http://www.ti.com http://www.fairchildsemi.com http://www.semiconductors.com http://www.onsemi.com Uwe.
