Figure 9-4. Multi-Voltage Translation with the LSF0108

9.2.3 Single Supply Translation

Sometimes, an external device will have an unknown voltage that could be above or below the desired

translation voltage, preventing a normal connection of the LSF. Resistors are added on the A side in place

of the second supply in this case – this is an example of when LSF single supply operation is utilized, shown in

Figure 9-5. In the following figure, a single 3.3 V supply is used to translate between a 3.3 V device and a device

that can change between 1.8 V and 5.0 V. R1 and R2 are added in place of the second supply. Note that due to

some current coming out of the Vref_A pin, this cannot be treated as a simple voltage divider.
