The FST16244 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 with four 4-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 the A and B Ports.
The document describes the Fairchild FST16244, a 16-bit bus switch organized as four separate 4-bit switches. It features high-speed CMOS operation that is TTL-compatible, designed to connect inputs to outputs without adding propagation delay or generating ground bounce noise. The device includes an active-low output enable input (OEn) to control the connection between Port A and Port B.
