- Figure 2. Level translation in one direction requires half of the open-drain translation circuit (a). For a low-to-high transition, RC effects do not appear until the output rises to about 0.5 V below the lower supply voltage (b). The circuit also works for transla
- Figure 3. The ultimate 1-to-5V up-shifting driver in the laboratory produces a symmetrical delay of 6 nsec using three-fourths of an MPQ2369 when driving a single 74AC541 buffer
