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 between 3V and 5V systems, but the results can be applied for interfacing between other voltage levels as well. We will discuss how one can ensure reliable information exchange and how to prevent current flow between both supply voltages when interfacing logic with memories, ASICs, PLDs and microproces... |
