1 1. Introduction
This user’s guide describes the TMUX741-746 evaluation module (EVM) and its intended use. This board allows for the quick prototyping and DC characterization of TI’s TMUX741x/TMUX746x Line of parts in either QFN (RRP) or TSSOP (PW) packages. Figure 1-1 and Figure 1-2 show the top and bottom sides of the board respectively.
