switches. Bus switch devices perform the function of connect-
ing 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. Without adequate bias on the gate-to-source junction
of the FET, the FET is turned off, therefore with no V
applied, the device has hot insertion capability.
between input and output ports reduces the delay in this path
to close to zero.
device, thus eliminating the need for external 25
resistors.
TTL- compatible ports that support 2 way bus exchange. The
BX pin controls the bus exchange and the BE pin serves as the
enable pin.
