IDT74FST32XL2384

NOTES:
1. Stresses greater than those listed under ABSOLUTE MAXIMUM RATINGS may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect reliability.
2. Vcc, Control, and Switch terminals.

The FST32XL2384 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 IDT74FST32XL2384 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 IDT74FST32XL2384 conducts and the resistance between input and output ports is small. Without adequate bias on the gateto- 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 of IDT74FST32XL2384 between input and output ports reduces the delay in this path to close to zero.

The FST32XL2384 is a 20-bit TTL-compatible bus switch. The BEx pins provide enable control.
