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 UHC
protection to support an extended
range of 2.0V below ground. Fairchild’s integrated Under-
shoot Hardened Circuit 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.
