FSTU6800

10-Bit Bus Switch with Precharged Outputs

and −2V Undershoot Protection

General Description

Features

■ 4Ω switch connection between two ports.

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 have “undershoot hardened” circuit protection to sup-

port an extended input range to 2.0V below ground. Fair-

■ Undershoot Hardened to -2.0V.

■ Soft enable turn-on to minimize bus-to-bus charge

sharing during enable.

■ Low l_CC

■ Zero bounce in flow-through mode.

child’s integrated Undershoot Hardened Circuit (UHC

)

■ Output precharge to minimize live insertion noise.

■ Control inputs compatible with TTL level.

■ See Applications Note AN-5008 for details.

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-kΩ resistor.
