FST16245 16-Bit Bus Switch April 2001 Revised April 2001 FST16245 16-Bit Bus Switch General Description Features The Fairchild Switch FST16245 provides 16-bits of high- � 4Ω switch connection between two ports. speed CMOS TTL-compatible bus switching. The low On � Minimal propagation delay through the switch. Resistance of the switch allows inputs to be connected to � Low l . CC outputs without adding propagation delay or generating � Zero bounce in flow-through mode. additional ground bounce noise. � Control inputs compatible with TTL level. 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.
