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.
