24-Bit Bus Switch with −2V Undershoot Protection
and Level Shifting
General Description
The Fairchild Switch FSTUD16211 provides 24-bits 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. A diode to VCC has been
integrated into the circuit to allow for level shifting between
5V inputs and 3.3V outputs.
The device is organized as a 12-bit or 24-bit bus switch.
When OE1 is LOW, the switch is ON and Port 1A is con-
nected to Port 1B. When OE2 is LOW, Port 2A is connected
to Port 2B. When OE1/2 is HIGH, a high impedance state
exists between the A and B Ports. The A and B Ports have
“undershoot hardened” circuit protection to support an
extended range to 2.0V below ground. Fairchild’s inte-
grated Undershoot Hardened Circuit (UHC) senses
undershoot at the I/O’s, and responds by preventing volt-
age differentials from developing and turning on the switch.
Features

Note 8: This parameter is guaranteed by design but is not tested. The bus switch contributes no propagation delay other than the RC delay of the typical On
Resistance of the switch and the 50pF load capacitance, when driven by an ideal voltage source (zero output impedance).
