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 FST163214 provides a 12-bit TTL- patible A port and three 12-bit TTL patible B ports. The S0-2 pins provide mux select and disable control. The A port can be connected to any one of the three B ports by selecting appropriate S0-2 states.
