The MAX4895E provides the level shifting necessary to
drive two standard VGA ports from a graphics controller
as low as +2.2V. Internal buffers drive the HSYNC and
VSYNC signals to VGA standard TTL levels. The DDC
switch provides level shifting by clamping signals to a
diode drop less than V

High-speed switches such as the MAX4895E require
proper PCB layout for optimum performance. Ensure
that impedance-controlled PCB traces for high-speed
signals are matched in length and are as short as pos-
sible. Connect the exposed pad to a solid ground
plane.
