SWITCH
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 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 FST163214 provides a 12-bit TTL- compatible A port
and three 12-bit TTL compatible B ports. The S
0-2 pins
provide mux select and disable control. The A port can be
connected to any one of the three B ports by selecting
appropriate S0-2 states.
DESCRIPTION:
The FST163214 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
