FST33X257
24:12 Multiplexer/Demultiplexer Bus Switch
General Description
The Fairchild Switch FST33X257 is a 24:12 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
x
is LOW, the select pin connects the A Port to
the selected B Port output. When OE
x
is HIGH, the switch
is OPEN and a high-impedance state exists between the
two ports.
