FSTU3257
Quad 2:1 Multiplexer/Demultiplexer Bus Switch with
2V Undershoot Protection
General Description
The Fairchild Switch FSTU3257 is a quad 2:1 high-speed
CMOS
TTL-compatible
multiplexer/demultiplexer
bus
switch. The low on resistance of the switch allows inputs to
be connected to outputs without adding propagation delay
or generating additional ground bounce noise.
When OE is LOW, the select pin connects the A Port to the
selected B Port output. The A and B Ports are “undershoot
hardened” with Undershoot Hardened Circuit (UHC®
¥) pro-
tection to support an extended range of 2.0V below
ground. Fairchild’s integrated UHC senses undershoot at
the I/O and responds by preventing voltage differentials
from developing and turning on the switch. When OE is
HIGH, the switch is OPEN and a high-impedance state
exists between the two ports.
Features
s Undershoot hardened to
2V (A and B Ports)
s Soft enable turn-on to minimize bus to bus charge
sharing during enable
s 4
: switch connection between two ports.
s Minimal propagation delay through the switch.
s Low lCC.
s Zero bounce in flow-through mode.
s Control inputs compatible with TTL level.
s See Applications Note AN-5008 for details
Ordering Code:
Device also available in Tape and Reel. Specify by appending suffix letter “X” to the ordering code.
