GENERAL DESCRIPTION
The AD8191A is an HDMI™/DVI switch featuring equalized TMDS® inputs and pre-emphasized TMDS outputs, ideal for systems with long cable runs. Outputs can be set to a high impedance state to reduce the power dissipation and/or to allow the construction of larger arrays using the wire-OR technique.
The AD8191A is provided in a 100-lead LQFP, Pb-free, surface mount package specified to operate over the −40°C to +85°C temperature range.
