The FST16245 is a 16-bit bus switch that provides high-speed CMOS TTL-compatible bus switching. The low On Resistance of the switch allows inputs to be connected to outputs without adding propagation delay or generating additional ground bounce noise. The device is organized as a 16-bit switch, consisting of two 8-bit switches with separate output enable inputs. When OE is LOW, the switch is ON and Port A is connected to Port B. When OE is HIGH, the switch is OFF and a high impedance state exists between Port A and Port B.
