Philips Semiconductors Application note Interfacing 3V and 5V applications Authors: Tinus van de Wouw (Nijmegen) / Todd Andersen (Albuquerque) 1.0 THE NEED FOR INTERFACING BETWEEN 3V AND 5V SYSTEMS Many reasons exist to introduce 3V1 systems, notably the lower power consumption for mobile applications and the introduction of parts that use technologies with such fine geometries that 5V is simply not allowed any more. The introduction of the 3V standard as supply voltage has resulted in many design activities for digital systems. Very often, however, there is a gradual transition from 5V to 3V, since not always are all required ponents available, or the system is rather plex so that...
