1 Introduction

TMUXHS221/LV is a high-speed bidirectional 2:1/1:2 mux/demux optimized for USB 2.0 and eUSB2 LS, FS, and HS signaling. TMUXHS221 and TMUXHS221LV offer different voltage levels for control logic and require different supply voltage values. TMUXHS221 supports differential and single ended CMOS signaling with a voltage range of −0.3 V to 3.6 V and 1.8 V control logic. TMUXHS221LV supports differential and single ended CMOS signaling with a voltage range of -0.3 V to 1.8 V and 1.2 V control logic. Figure 1-1 shows that both devices provide switching on differential channels between Port D to DA or Port D to DB.
