DESCRIPTION
The HD3SS212 is a high-speed passive switch capable of switching two full DisplayPort 4 lane ports from one of
two sources to one target location in an application. For DisplayPort Applications that HD3SS212 also supports
switching of the Auxiliary (AUX) and Hot Plug Detect (HPD) signals. HPD path is a buffer which requires a 125kΩ
pull-down resistor on the HPDC line.
A typical application would be a mother board that includes two GPUs that need to drive one DisplayPort sink.
The GPU is selected by the Dx_SEL pin. The HD3SS212 is offered in a 48-ball BGA package and specified to
operate from a single supply voltage of 3.3V over full industrial temperature range of –40°C to 105°C.

ACTIVE: Product device recommended for new designs.
LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.
NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design.
PREVIEW: Device has been announced but is not in production. Samples may or may not be available.
OBSOLETE: TI has discontinued the production of the device.

Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check http://www.ti.com/productcontent for the latest availability
information and additional product content details.
TBD: The Pb-Free/Green conversion plan has not been defined.
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements for all 6 substances, including the requirement that
lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.
Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and package, or 2) lead-based die adhesive used between
the die and leadframe. The component is otherwise considered Pb-Free (RoHS compatible) as defined above.
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame retardants (Br or Sb do not exceed 0.1% by weight
in homogeneous material)
