FST6800 10-Bit Bus Switch with Precharged Outputs June 1997 Revised November 2000 FST6800 10-Bit Bus Switch with Precharged Outputs General Description Features The Fairchild Switch FST6800 provides 10-bits of high-4Ω switch connection between two ports. speed CMOS TTL-compatible bus switching. The low onMinimal 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. The device precharges the B Port to a selectable bias voltage (BiasV) to minimizeOutput precharge to minimize live insertion noise. live insertion noise. Control inputs compatible with TTL level. 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.
