Detailed Description
The MAX4885E integrates high-bandwidth analog
switches and level-translating buffers to implement a
complete 1:2 multiplexer for VGA signals. The device
provides switching for RGB, HSYNC, VSYNC, SDA_
and SCL_ signals.
The HSYNC and VSYNC inputs feature level-shifting
buffers to support TTL output logic levels from low-volt-
age graphics controllers. These buffered switches may
be driven from as little as +2.0V up to +5.5V. RGB sig-
nals are routed with the same high-performance analog
switches, and SDA_, SCL_ signals are voltage clamped
to a diode drop less than VL. Voltage clamping pro-
vides protection and compatibility with SDA_ and SCL_
signals and low-voltage ASICs. In keyboard/video/
mouse (KVM) applications, VL is normally set to +5V
because low-voltage clamping is not required, as spec-
ified by the VESA standard.
Drive EN logic-low to shut down the MAX4885E. In shut-
down mode, all switches are high impedance, providing
high-signal rejection. The RGB, HSYNC, VSYNC, SDA_,
and SCL_ outputs are ESD protected to ±15kV by the
Human Body Model.
RGB Switches
The MAX4885E provides three SPDT high-bandwidth
switches to route standard VGA R, G, and B signals
(see Table 1). The R, G, and B analog switches are
identical, and any of the three switches can be used to
route red, green, or blue video signals.
