FST3253MX Datasheet PDF - ON Semiconductor

●The FST3253MX is a 4:1 dual CMOS multiplexer/demultiplexer Bus Switch provides TTL-compatibility. 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.
