FST32253 Dual 4:1 Multiplexer/Demultiplexer Bus Switch with 25Ω Series Resistor in Outputs August 2001 Revised September 2001 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-patible 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...
