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
bus
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, S0 and S1 connect the A Port to the
selected B Port output. When OE is HIGH, the switch is
OPEN and a high-impedance state exists between the two
ports.
Features
s 4
switch connection between two ports.
s Minimal propagation delay through the switch.
s Low lCC.
s Zero bounce in flow-through mode.
s Control inputs compatible with TTL level.
Ordering Code:
Device also available in Tape and Reel. Specify by appending suffix letter “X” to the ordering code.
