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 FST163233 provides three 16-bit TTL-patible ports that support 2:1 multiplexing. The SEL0,1 and TEST0,1 pins provide switch enable and mux select control as shown below. The A port can be connected to port 1B or port 2B or both ports 1B and 2B.
