The LSF family can also be used for multi-voltage translation, where each channel of a single LSF device can drive to different supply voltages. In this example, the A-side is connected to a microcontroller operating at 3.3 V. The B-side has three different target devices, with V_CC of 5 V, 1.8 V, and 1.2 V on the three different channels. These B-side voltages are set by different pull-up resistors on each channel, with the exception of the 1.2 V channel that will not require a pull-up resistor. Unlike the two-voltage example previously shown, for multi-voltage systems VRef_A must be set to the lowest VCC in the system, in this case, 1.2 V. This is the reason that no pull-up resistor is needed for the 1.2 V B-side channel, as the pass transistor will follow VGate voltage minus V threshold which equals 1.2 V. A high-level signal from the microcontroller will shut down the pass transistor, allowing each of the B-side channels to be pulled to the correct voltage. A low-level signal from the microcontroller will cause the pass transistor to conduct, pulling each of the B-side channels low.
