FSTD16861
20-Bit Bus Switch with Level Shifting
General Description
The Fairchild Switch FSTD16861 provides 20-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 V
CC
has been
integrated into the circuit to allow for level shifting between
5V inputs and 3.3V outputs.
The device is organized as a 10-bit or 20-bit bus switch.
When OE
1
is LOW, the switch is ON and Port 1A is con-
nected to Port 1B. When OE
2
is LOW, Port 2A is connected
to Port 2B. When OE
X
is HIGH, a high impedance state
exists between the A and B Ports.
