DESCRIPTION:
devices 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 be-
tween 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.
output ports reduces the delay in this path to close to zero.
the A and B ports are isolated, and the B port's pins are precharged to the
bias voltage through the equivalent of a 10KΩ resistor on each B port pin.
