20-BIT, TWO PORT BUS
SWITCH WITH RESISTOR
DESCRIPTION:
The FST1632861 belongs to IDT's famly of Bus switches. Bus switch
devices performthe 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. 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 FST1632861 bus switch has a built-in 28
Ω
series resistor to reduce
noise which can result fromreflections. This 28
Ω
built-in series resistor
elimnates the need for an external termnating resistor.
