ADVANCE INFORMATION
9-BIT BUS EXCHANGE
SWITCH
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. 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 FST163209 provides four 9-bit TTL- compatible ports
that support 2 way bus exchange. The S
0-2 pins control the
bus exchange and switch enable functions.
