FST16212 24-Bit Bus Exchange Switch
July 1997
Revised April 2005
FST16212
24-Bit Bus Exchange Switch
General Description
The Fairchild Switch FST16212 provides 24-bits of high-
speed CMOS TTL-compatible bus switching or exchang-
ing. 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 operates as a 24-bit bus switch or a 12-bit bus
exchanger, which allows data exchange between the four
signal ports via the data-select terminals.

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:
The input and output negative voltage ratings may be exceeded if
the input and output diode current ratings are observed.
Note 3:
Unused control inputs must be held high or low. They may not float.
