Often, it becomes necessary to interface an existing or new 5V AVR / PIC / MCU project to new devices that use 3.3V logic, like memory cards, sim cards, etc. Described here is a circuit that converts ...

Linear Technology Corporation introduces the LTC6957, a DC to 300MHz dual output buffer/driver/logic translator, ideal for converting sine waves into low phase noise logic level signals. The LTC6957, ...

As we have observed in previous parts of this course, in a digital system, signals can take on only two values: high or low. These values are often represented by two voltage levels. The most used ...
