FST32211
40/48-Bit Bus Switch
General Description
The Fairchild Switch FST32211 provides up to 48-bits of
high-speed CMOS TTL-compatible bus switching. The low
On Resistance of the switch allows inputs to be connected
to outputs without adding propagation delay or generating
additional ground bounce noise.
The device can be organized as four 12-bit, two 24-bit, or
one 48-bit bus switch. When routed as a 40-bit bus switch,
the device can be organized as four 10-bit, two 20-bit or
one 40-bit bus switch. When OE1 is LOW, the switch is ON
and Port 1A is connected to Port 1B. When OE2 is LOW,
the switch is ON and Port 2A is connected to Port 2B.
When OE3 is LOW, the switch is ON and Port 3A is con-
nected to Port 3B. When OE4 is LOW, the switch is ON and
Port 4A is connected to Port 4B. When OE1, OE2, OE3, or
OE4 are HIGH, a high impedance state exists between the
A and B Ports.
Features
I 4switch connection between two ports
I Minimal propagation delay through the switch
I Low lCC
I Zero bounce in flow-through mode

Note 3: The Absolute Maximum Ratingsare those values beyond which
the safety of the device cannot be guaranteed. The device should not be
operated at these limits. The parametric values defined in the Electrical
Characteristics tables are not guaranteed at the absolute maximum rating.
The Recommended Operating Conditionstable will define the conditions
for actual device operation.
Note 4: VS is the voltage observed/applied at either A or B Ports across the
switch.
Note 5: The input and output negative voltage ratings may be exceeded if
the input and output diode current ratings are observed.
Note 6: Unused control inputs must be held HIGH or LOW. They may not
float.
