DESCRIPTION:
The FST163232 belong 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 V
CC
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 FST163232 provides three 16-bit TTL- compatible
ports that support 2:1 multiplexing. The S
0,1
pins control mux
select and switch enable/disable. The S
0,1
inputs are syn-
chronous and clocked on the rising edge of CLK when
CLKEN
is low.
Port A can be connected to port B1 or port B2 or both ports
B1 and B2.
