MAX9132/MAX9134/MAX9135
The MAX9132/MAX9134/MAX9135 high-speed, multi-
ple-port, low-voltage differential signaling (LVDS) cross-
bar switches are specially designed for digital video
and camera signal transmission. These switches have a
wide bandwidth, supporting data rates up to 840Mbps.
The MAX9132 has three input ports and two output
ports, the MAX9134 has three input ports and four out-
put ports, and the MAX9135 has four input ports and
three output ports. The digital video or camera signal
can go through the switches from an input port to one
or multiple output ports.
The MAX9132/MAX9134/MAX9135 switch routing is
programmable through either an I
2
C interface or a
Local Interconnect Network (LIN) serial interface. In
addition, the MAX9134/MAX9135 provide pins to set
switch routing. These pins also set the initial conditions
for the I
2
C mode. To generate more input or output
ports, these switches can be connected in parallel or in
cascade.
The MAX9132/MAX9134/MAX9135 operate from a
+3.3V supply and are specified over the -40°C to
+105°C temperature range. The MAX9134/MAX9135
are available in a 32-pin (5mm x 5mm) TQFP package,
while the MAX9132 is available in a 20-pin (6.5mm x
4.4mm) TSSOP package. The input/output port pins are
rated up to ±25kV ESD for the ISO Air-Gap Discharge
Model, ±15kV ESD for the IEC Air-Gap Discharge
Model, and ±10kV for the ESD Contact Discharge
Model. All other pins support up to ±3kV ESD for the
Human Body Model.

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.
