DESCRIPTION:
The FST3861 belongs to IDT’s family of Bus switches. Bus
switch devices perform the function of connecting or isolating
two ports without providing any inherent current sink or source
capability. 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 ad-
equately forward-biased, the device conducts and the resis-
tance between input and output ports is small. Without ad-
equate bias on the gate-to-source junction of the FET, the
FET is turned off, therefore with no VCC applied, the device
has not insertion capability.
The low on-resistance and simplicity of the connection be-
tween input and output ports reduces the delay in this path to
close to zero.
