IDT74FST6800
FEATURES:
• Bus switches provide zero delay paths
• Low switch on-resistance: 7Ω
• TTL-compatible input and output levels
• ESD > 2000V per MIL-STD-883, Method 3015; > 200V using
machine model (C = 200pF, R = 0)
• Available in QSOP and TSSOP packages
DESCRIPTION:
The FST6800 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 FST6800 provides a 10-Bit TTL-compatible interface. The ON pin
serves as the enable pin. When ON is high, A and B ports are isolated and
B outputs are precharged to the BIASV voltage, through the equivalent of
a 10KΩ resistor.
