ADVANCE INFORMATION

16-BIT SYNCHRONOUS

2:1 MUX/DEMUX SWITCH

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. With-

out adequate bias on the gate-to-source junction of the FET,

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 FST163232 provides three 16-bit TTL- compatible

chronous and clocked on the rising edge of CLK when

is low.

Port A can be connected to port B1 or port B2 or both ports

B1 and B2.

DESCRIPTION:

The FST163232 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
