This page has a range of tutorial pages written to help circuit design on a range of topics. There are connection details and explanations on how to use them. Some include examples of useful circuits and how to connect devices together, such as counters and dividers in synchronous and asychronous (ripple) configuration.
I have included some simulation circuits using Crocodile Clips (c) and Livewire (c) software available for download also.
There are only a few so far but more will be added as time allows. There are links to these tutorials on other pages where relevant. Most IC's covered are of CMOS type.
