FAIRCHILD FST3126 handbook

The FST3126 is a quad high-speed CMOS TTL-compatible bus switch that provides low on-resistance and minimal propagation delay, allowing inputs to be connected to outputs without adding delay or generating additional ground bounce noise. The device consists of four 1-bit switches with separate OE inputs. When OE is high, the switch is on and Port A is connected to Port B. When OE is low, the switch is open and a high-impedance state exists between the two ports.
