FST16245 16-Bit Bus Switch April 2001 Revised June 2005 FST16245 16-Bit Bus Switch General Description The Fairchild Switch FST16245 provides 16-bits of highspeed 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. There are 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 the A and B Ports. Features s 4: switch connection between two ports. s Minimal propagation delay through the switch. s Low lCC. s Zero bounce in flow-through mode. s Control inputs compatible with TTL level.
