FSTU6800
10-Bit Bus Switch with Pre-Charged Outputs
and
2V Undershoot Hardened Circuit (UHC
) Protection
General Description
The Fairchild Switch FSTU6800 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. Both the A Ports and the B
Ports are “undershoot hardened” with UHC
protection to
support an extended input range to 2.0V below ground.
Fairchild’s integrated Undershoot Hardened Circuit, UHC
senses undershoot at the I/Os, and responds by preventing
voltage differentials from developing and turning on the
switch. The device also precharges the B Port to a select-
able 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-k
resistor.
