OCTAL BUS SWITCH
DESCRIPTION:
The FST3244 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
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 or 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 FST3244 is an octal TTL-compatible bus switch. The
OE pins
provide output enable control for all 8 bits. This device is pin-compatible
with and functionally similar to the FCT244T.
