FST3253 − Dual 4:1 Multiplexer/Demultiplexer Bus Switch

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.
