FST16862 20-Bit Bus Switch October 2001 Revised February 2002 FST16862 20-Bit Bus Switch General Description The Fairchild Switch FST16862 provides 20-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 20-bit bus switch. When OEX is LOW, the switch is ON and Port A is connected to Port B. When OEX is HIGH, a high impedance state exists between the A and B Ports. Features I 4Ω switch connection between two ports. I Minimal propagation delay through the switch. I Low lCC. I Zero bounce in flow-through mode. I Control inputs compatible with TTL level.
