FST32253
Dual 4:1 Multiplexer/Demultiplexer Bus Switch
with 25Ω Series Resistor in Outputs
General Description
The Fairchild Switch FST32253 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.
The FST32253 has an equivalent 25Ω series resistor to
reduce signal-reflection noise, eliminating the need for
external terminating resistors.
Features
s 25Ω 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
