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 FST1632xxx integrates terminating resistors in the device, thus eliminating the need for external 25Ω series resistors. The FST163384 and FST1632384 are 20-bit TTL-patible bus switches. The BEx pins provide enable control. FUNCTIONAL BLOCK DIAGRAM A0 B0 A10 B10 A4 B4 A14 B14 A5 B5 A15 B15 A9 BEA BEB B9 A19 BEC...
