FUNCTIONAL BLOCK DIAGRAM
IDT74FST163244
16-BIT BUS SWITCH
DESCRIPTION:
The FST163244 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. 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.
Thelowon-resistanceandsimplicityoftheconnectionbetweeninputand
output ports reduces the delay in this path to close to zero.
The FST163244 is pin-compatible with and functionally similar to the
FCT16244T.
