ADG3241  
Bus Isolation  
There are many systems, such as docking stations, PCI boards  
for servers, and line cards for telecommunications switches, that  
require the ability to handle hot swapping. If the bus can be  
isolated prior to insertion or removal, there is more control over  
the hot swap event. This isolation can be achieved using bus  
switches. The bus switches are positioned on the hot swap card  
between the connector and the devices. During hot swap, the  
ground pin of the hot swap card must connect to the ground pin  
of the backplane before any other signal or power pins.  
A common requirement of bus architectures is low capacitance  
loading of the bus. Such systems require bus bridge devices that  
extend the number of loads on the bus without exceeding the  
specifications. Because the ADG3241 is designed specifically for  
applications that do not need drive yet require simple logic  
functions, it solves this requirement. The device isolates access  
to the bus, thus minimizing capacitance loading.

Analog Switching  
Bus switches can be used in many analog switching applications,  
for example, video graphics. Bus switches can have lower on  
resistance, smaller ON and OFF channel capacitance, and thus  
improved frequency performance than their analog counterparts.  
The bus switch channel itself, consisting solely of an NMOS  
switch, limits the operating voltage (see TPC 1 for a typical  
plot), but in many cases, this does not present an issue.

Isolation Application  
High Impedance During Power-Up/Power-Down  
To ensure the high impedance state during power-up or power-  
down, BE should be tied to VCC through a pull-up resistor; the  
minimum value of the resistor is determined by the current-  
sinking capability of the driver.  
Hot Plug and Hot Swap Isolation  
The ADG3241 is suitable for hot swap and hot plug applications.  
The output signal of the ADG3241 is limited to a voltage that is  
below the VCC supply, as shown in Figures 6, 8, and 10. Therefore  
the switch acts like a buffer to take the impact from hot insertion,  
protecting vital and expensive chipsets from damage.  
In hot plug applications, the system cannot be shut down when  
new hardware is being added. To overcome this, a bus switch can  
be positioned on the backplane between the bus devices and the  
hot plug connectors. The bus switch is turned off during hot plug.  
Figure 12 shows a typical example of this type of application.
