2V Undershoot Protection
General Description
The Fairchild Switch FSTU16862 provides 20-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 is organized as a 20-bit bus switch. When OE
X
is LOW, the switch is ON and Port A is connected to Port B.
When OE
X
is HIGH, a high impedance state exists
between the A and B Ports. The A and B Ports are pro-
tected against undershoot to support an extended range to
2.0V below ground. Fairchild鈥檚 integrated Undershoot
Hardened Circuit (UHC
铮?/div>
) senses undershoot at the I/O
and responds by preventing voltage differentials from
developing and turning the switch on.
