FST6800 10-Bit Bus Switch with Pre-Charged Outputs June 1997 Revised December 1999 FST6800 10-Bit Bus Switch with Pre-Charged Outputs General Description The Fairchild Switch FST6800 provides 10-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 precharges the B Port to a selectable bias voltage (BiasV) to minimize live insertion noise. The device is organized as a 10-bit switch with a bus enable (OE) signal. When OE is LOW, the switch is ON and Port A is connected to Port B. When OE is HIGH, the switch is OPEN and the B Port is precharged to BiasV through an equivalent 10-kΩ resistor. Features s 4Ω switch connection between two ports. s Minimal propagation delay through the switch. s Low lCC. s Zero bounce in flow-through mode. s Output precharge to minimize live insertion noise. s Control inputs compatible with TTL level.
