FSTU162450
Configurable 4-Bit to 20-Bit Bus Switch with
2V Undershoot Protection
and 25
Series Resistors in Outputs (Preliminary)
General Description
The Fairchild Universal Bus Switch FSTU162450 provides
4-bit, 5-bit, 8-bit, 10-bit, 16-bit, 20-bit 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 FSTU162450 is designed to allow “customer” configu-
ration control of the enable connections. The device can be
organized as either a five 4-bit, four 5-bit, two 10-bit or one
20-bit enable bus switch. Also achieveable are 8-bit and
16-bit enabled configurations (see Functional Description).
The device’s bit configuration is controlled through select
pin logic. (see Truth Table). When OE
x
is LOW, Port A
x
is
connected to Port B
x
. When OE
x
is HIGH, the switch is
OPEN.
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.

Applications Note
Select pins S

are intended to be used as static
user configurable control pins. The AC performance of
these pins has not been characterized or tested. Switching
of these select pins during system operation may tempo-
rarily disrupt output logic states and/or enable pin controls.
