AN240, Interfacing 3V and 5V Applications

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 de

* can only be made with 3V. Or vice versa! With the introduction of new standards such as 2.2-2.7V or even 1.7V we expect that interfacing between systems that use different supply voltages will be an actual issue for many years to come. This application note specifically addresses the interfacing bet
