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
applied, the device has hot insertion capability.
between input and output ports reduces the delay in this path
to close to zero.
