DESCRIPTION
The TS3DV642 is a 12 channels 1:2 or 2:1 bi-
directional multiplexer/demultiplexer. The TS3DV642
operates from a 2.6 to 4.5 V supply, making it
suitable for battery-powered applications. It offers low
and flat ON-state resistance as well as low I/O
capacitance which allow it to achieve a typical
bandwidth of up to 7.5 GHz. The device provides the
high bandwidth necessary for HDMI and DisplayPort
applications.
The TS3DV642 offers a power-down mode, in which
all channels become high-Z and the device operates
with minimal power.
