The Fairchild Switch FST3253 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.
