ideal for routing USB data lines (see Figure 7) and for
applications that require switching between multiple
USB hosts (see Figure 8). The MAX4907/MAX4907F
can be used in applications that require different data
types to share the same pins (see Figure 9); however,
the shared device must be capable of going into the tri-
state mode. The MAX4906F/MAX4907F also feature
+5.5V fault protection to guard systems against shorts
to the USB bus voltage. The fault-protected versions
are recommended for all USB applications.
Ethernet Switching
The wide bandwidth of the MAX4906/MAX4906F/
MAX4907/MAX4907F meets the needs of 10/100 Ethernet
switching. These devices switch the signals from two
interface transformers and connect the signals to a single
10/100 Base-T Ethernet PHY, simplifying docking station
design and reducing manufacturing costs.
Power-Supply Sequencing
Caution: Do not exceed the absolute maximum rat-
ings because stresses beyond the listed ratings
may cause permanent damage to the device.
Proper power-supply sequencing is recommended for
all CMOS devices. Always apply V+ before applying
analog signals, especially if the analog signal is not
current limited.
Layout
High-speed switches require proper layout and design
procedures for optimum performance. Keep design-
controlled-impedance PC board traces as short as pos-
sible. Ensure that bypass capacitors are as close to the
device as possible. Use large ground planes where
possible.
