IDT74FST163233 General Description

    The FST163233 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 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-compatible ports that support 2:1 multiplexing. The SEL_0,1 and TEST_0,1 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.

IDT74FST163245 General Description

    The FST163245/163P245 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.

    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 FST163245 and FST163P245 are 16-bit TTL-compatible bus switches. The OE pins provide enable control. The FST163P245 supports precharge on the B port. So when OE is high, A and B ports are isolated and B outputs are precharged to the bias voltage through the equivalent of a 10KΩ resistor (1B1-8 precharged to VBIAS1 and 2B1-8 precharged to VBIAS1).
