Obviously there was nothing to talk about until you sent your message... :-) I would like to ask a question. In the most recent Maplin catalogue they have started going overboard with all the numbers and letters that surround the IC names, so that for example "74LS00" becomes something like "SN74LS00N". In some of the sections, they have started saying: Also available in SMD: PC74HC00M1R or something remotely like that, and they have two versions of the IC, one with the above number and one differing from that in one or more letters. What on earth is SMD? Also, can someone tell me what the difference is between the two octal D-latches they seem to have? I think one is 74HC574 and the other is 74HC374, but I could be wrong. The descriptions of these two things which are on different pages seem to describe exactly the same device. imc
