4-BIT BUS SWITCH
DESCRIPTION:
The FST3125 belong 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 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.
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 FST3125 is a 4-bit TTL-compatible bus switch. The x
OE pins
provide individual enable control for each of the four bits.
