Configuring The System To Translate Voltages From High To Low Or From Low To High, According To The Recommended Guidelines For The Input And Output Voltage Levels Of Each Component, Makes The System More Predictable, Improves Overall Performance, And Saves Energy.

Then the voltage across the voltage divider is divided into four reference points, vt/4. To get over this obstacle you need a device that can shift 3.3v up to 5v or 5v down to 3.3v. This the recommended method to level shift signals that require high speed communication (serial at a high baud rate, i2c, etc…).

The Simplest Way Is To Use Resistors, Where Signal Levels Differ.

Connect vcc to your logic level you want to convert to (say 3.3v), ground connects to ground. The voltage doubler is the first block and in this ic, a switched capacitor method is utilized to make the voltage twice. Level shifting is a dilemma so common we designed a simple pcb assembly to make interfacing devices a little easier:
