It is the responsibility of engineers to get the most
performance and capability out of the resources
available. In this application note, we present ideas that
have helped previous designs reduce size and cost.
This application note looks at different ways of:
• saving input pins
• driving multiple LEDs
• saving output pins
• maximizing pin usage
• power saving tricks AN234
