The Fairchild Switch FST3257 is a quad 2:1 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, the select pin connects 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.
