For that reason, we like using the 4050\/74LVX245 series and similar logic to perform proper level shifting. The only problem is that they are only good in one direction which can be a problem for some speciality bi-directional interfaces and also makes wiring a little hairy.\u003cbr\u003e\u003cbr\u003eThat's where this lovely chip, the TXB0104 bi-directional level converter comes in!

This makes the ChronoDot very well suited for time critical applications that cannot be regularly synchronized to an external clock.
