FSTU32X384
20-Bit Low Power Bus Switch
with
2V Undershoot Protection
General Description
The Fairchild Switch FSTU32X384 provides 20 bits of high-
speed CMOS TTL-compatible bus switches. 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 four 5-bit switches with separate bus enable (OE) sig-
nals. When OE is LOW, the switch is ON and Port A is con-
nected to Port B. When OE is HIGH, the switch is OPEN
and a high-impedance state exists between the two ports.
The A and B Ports are protected against undershoot to
support an extended range to 2.0V below ground.
Fairchild’s
integrated
Undershoot
(UHC
) senses undershoot at the I/O and responds by
preventing voltage differentials from developing and turn-
ing the switch on.
