18-BIT BUS SWITCH/
4 PORT BUS EXCHANGER
DESCRIPTION:
The FST163209 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. Thus they
generate little or no noise of their own while providing a low resistance path
foranexternaldriver. Thesedevicesconnectinputandoutputportsthrough
an n-channel FET. When the gate-to-source junction of this FET is
adequately forward-biased the device conducts and the resistance be-
tween 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 FST163209 operates as an 18-it bus switch or a 9-bit, 4 port bus
exchanger.
