FSTUD16450 Configurable 4-Bit to 20-Bit Bus Switch with -2V Undershoot Protection and Selectable Level
Shifting
January 2001
Revised August 2001
FSTUD16450
Configurable 4-Bit to 20-Bit Bus Switch with
-2V Undershoot Protection and Selectable Level Shifting
General Description
The Fairchild Universal Bus Switch FSTUD16450 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 FSTUD16450 is designed to allow 鈥渃ustomer鈥?configu-
ration control of the enable connections. The device is
organized as either a 4-bit, 5-bit, 10-bit or 20-bit bus switch.
8-bit and 16-bit configurations are also achievable (see
Functional Description). The device's bit configuration is
chosen 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 鈥渦ndershoot hardened鈥?with UHC
錚?/div>
protection to support an extended range to 2.0V below
ground. Fairchild's integrated 鈥淯ndershoot Hardened
Circuit鈥?(UHC) senses undershoot at the I/O's, and
responds by preventing voltage differentials from develop-
ing and turning on the switch.
Another key device feature is the addition of a level shifting
select pin, 鈥淪
2
鈥? When S
2
is LOW, the device behaves as a
standard N-MOS switch. When S
2
is HIGH, a diode to V
CC
is integrated into the circuit allowing for level shifting
between 5V inputs and 3.3V outputs.

Applications Note
Select pins S

, 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.
