Guide

There are four separate data channels on the BD-LLC, each capable of shifting data to and from high and
low voltages. These pins are labeled HV1  , LV1  , HV2  , LV2  , HV3  , LV3  , HV4  , and LV4  . The number at the
end of each label designates the channel of the pin, and the HV  or LV  prefix determines whether it’s on
the high or low side of the channel.
A low-voltage signal sent in to LV1  , for example, will be shifted up to the higher voltage and sent out HV1  .
Something sent in HV3  will be shifted down and sent out of LV3  . Use as many of these channels as your
project requires. You don’t have to use every single one.
Keep in mind that these level shifters are purely digital. They can’t map an analog voltage from one max
voltage to another.
Hookup Examples
Assembly
Before you can plug the converter into your system, you’ll need to solder something into it. There are a lot
of options here. You could solder straight male headers in, and plug it right into a breadboard. Or perhaps
you want to solder wires directly into it. Pick an assembly method that melds with how you intend to use
the board.
