The CBTL06141 uses a 3.3 V power supply. All main signal paths are implemented using
high-bandwidth pass-gate technology and are non-directional. No clock or reset signal is
needed for the multiplexer to function.
The switch position for the main channels is selected using the select signal GPU_SEL.
Additionally, the signal DDC_AUX_SEL selects between AUX and DDC positions for the
DDC / AUX channel. The detailed operation is described in
The internal multiplexer switch position is controlled by two logic inputs GPU_SEL and
DDC_AUX_SEL as described below.
