The ON Semiconductor Switch FST6800 provides 10-bits of high-speed 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 (Bias V) 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-kohm resistor.
