FST3253
Dual 4:1 Multiplexer/Demultiplexer Bus Switch
General Description
The Fairchild Switch FST3253 is a dual 4:1 high-speed
CMOS
TTL-compatible
multiplexer/demultiplexer
switch. The low on resistance of the switch allows inputs to
be connected to outputs without adding propagation delay
or generating additional ground bounce noise.
When OE is LOW, S
and S
connect the A Port to the
0
1
selected B Port output. When OE is HIGH, the switch is
OPEN and a high-impedance state exists between the two
ports.
