DIL/NetPC ADNP/1486-3V: 5 V Tolerance

It is to be considered, however, that the DIL/NetPC ADNP/1486-3V is a 3.3 volt- based system. The output levels are derived from the 3.3 volt supply voltage. Not all inputs of the DIL/NetPC ADNP/1486-3V can be driven by external 5 volt components. For more details, see the following table.
