How can I reduce my standby power consumption?
... There are a series of common causes for this behaviour, some more easily dealt with than others. Each one will be dealt with in turn, explaining the problem and offering a solution. Floating Inputs This is by far the most common cause of high power consumption. CMOS inputs consume very little power ...
