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 OE
1
is LOW, the switch is ON
and Port 1A is connected to Port 1B. When OE
2
is LOW,
the switch is ON and Port 2A is connected to Port 2B.
When OE
3
is LOW, the switch is ON and Port 3A is con-
nected to Port 3B. When OE
4
is LOW, the switch is ON and
Port 4A is connected to Port 4B. When OE
1
, OE
2
, OE
3
, or
OE
4
are HIGH, a high impedance state exists between the
A and B Ports.
