FST16861 20-Bit Bus Switch
March 2000
Revised June 2005
FST16861
20-Bit Bus Switch
General Description
The Fairchild Switch FST16861 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.
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.
Features

Note 1:
The “Absolute Maximum Ratings” are those values beyond which
the safety of the device cannot be guaranteed. The device should not be
operated at these limits. The parametric values defined in the Electrical
Characteristics tables are not guaranteed at the absolute maximum rating.
The “Recommended Operating Conditions” table will define the conditions
for actual device operation.
Note 2:
V
S
is the voltage observed/applied at either the A or B Ports across
the switch.
Note 3:
The input and output negative voltage ratings may be exceeded if
the input and output diode current ratings are observed.
Note 4:
Unused control inputs must be held HIGH or LOW. They may not
float.
