MAX4886 Summary of contents
Page 1
... The MAX4886 connects either one monitor to one of two digital video signals, or one HDMI/DVI source to one of two loads (sink). The MAX4886 set of differential switches is based on an nFET architecture with internal charge pump for gate overdrive. This advanced architecture results in an extremely low capacitance and on-resistance needed for the excellent return loss requirements for digital switching ...

... GND are clamped by internal diodes. Limit forward-diode current to maximum current rating. DD Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability ...

... OUT- NC1- Figure 3. Skew Measurements Additional Applications In a typical application (see Figure 5), the MAX4886 and MAX4929 are used to route the TMDS signals and low-frequency signals between two HDMI inputs. In another application (see Figure 6), the MAX4886 is used in a notebook to route high-frequency DVI port on the computer or to the connector on the docking sta- tion ...
