V+, VL, and CLP to GND using 0.1µF or larger ceramic
capacitors as close to the device as possible.
The MAX4929E is designed for HDMI/DVI switching.
The MAX4929E permits hot-plugging to any inputs/
outputs regardless of the power status of the device.
A plug can be inserted, and thus connected to the
MAX4929E whether the device is powered up or not.
Therefore, sequencing of power supplies is not
required; V+, CLP, and VL can be applied in any order.
Two MAX4929Es can be connected together to form a
4:1 switch (see Figure 6).
The MAX4929EETP+ provides an EP to improve thermal
performance in the TQFN package. Connect the EP to
GND or leave EP unconnected.
