Figure 10. ADG3243 in a Hot Plug Application
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.
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.
High Impedance during Power-Up/Power-Down
To ensure the high impedance state during power-up or power-
down,
BEx should be tied to V
CC through a pull-up resistor; the
minimum value of the resistor is determined by the current-
sinking capability of the driver.
