DESCRIPTION:
perform the function of connecting or isolating two ports without providing
any inherent current sink or source capability. Thus they generate little or
no noise of their own while providing a low resistance path for an external
driver. These devices connect input and output ports through an n-channel
FET. When the gate-to-source junction of this FET is adequately forward-
biased the device conducts and the resistance between input and output
ports is small. Without adequate bias on the gate-to-source junction of the
FET, the FET is turned off, therefore with no V
hot insertion capability.
output ports reduces the delay in this path to close to zero.
serves as the enable pin. When ON is high, A and B ports are isolated and
B outputs are precharged to the BIASV voltage, through the equivalent of
a 10KΩ resistor.

... Since this time is constant and much smaller than the rise/fall times of typical driving signals, it adds very little propagation delay to the system. Propagation delay of the bus switch when used in a system is determined by the driving circuit on the driving side of the switch and its interaction with the load on the driven side ...
