DESCRIPTION:
The FST163233 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. 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. With-
out adequate bias on the gate-to-source junction of the FET,
the FET is turned off, therefore with no VCC applied, the device
has hot insertion capability.
The low on-resistance and simplicity of the connection
between input and output ports reduces the delay in this path
to close to zero.
The FST163233 provides three 16-bit TTL-compatible
ports that support 2:1 multiplexing. The SEL0,1 and TEST0,1
pins provide switch enable and mux select control as shown
below.
The A port can be connected to port 1B or port 2B or both
ports 1B and 2B.
