G GST_Nem New Member Dec 16, 2005 #1 is there a chip which counts pulses into binary and them decodes them into seven segment display and then also resets to 0 at 9? or do i need to use binary counter, BCD and a load of logic?

R Russlk New Member Dec 16, 2005 #2 All you need is a BCD counter like CD4510, 4522, 4518, 4553 and a BCD to 7-segment decoder like CD4511, 4543, or 4558.

G GST_Nem New Member Dec 16, 2005 #3 ok well how can i get that combination to count to 0-9 then reset to 0? does the bcd do it auto?
G GST_Nem New Member Dec 16, 2005 #5 what is the msb/carry output ? sorry about all the annoying question but im not good with counters. also what reset? to the BCD? does a decoder even have a reset?
