We recently bought some shift registers from Farnell but being SMT they’re not easy to use on a breadboard /prototyping system so we knocked up a simple breakout board for them. These boards should suffice for any SOIC device, to make it suitable for plugging into a breadboard.

Interestingly, the parts are listed as SOP-sized but in ExpressPCB there were no component layouts for SOP. We chose SOIC instead and the layout was a perfect match. So is SOP and SOIC the same layout? The jury’s still out on that one.

In the meantime, here’s our breakout board layout.
