The IC CD4017 is used for counting applications, it has the capability to turn on 10 outputs sequentially in a pre-defined time and reset the count or hold it when required. It also has the capability to indicate the status of counting using a Carry pin. This is commonly used for Led chasers and other logical output projects, so if you are looking for a sequential decoded counting IC that can count up to 10 then this IC will be your right choice.
