FST16209  
18-Bit Bus Exchange Switch  
General Description  
Features  
The Fairchild Switch FST16209 provides 18-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.  
4switch connection between two ports.  
Minimal propagation delay through the switch.  
Low lCC  
.
Zero bounce in flow-through mode.  
Control inputs compatible with TTL level.  
The device operates as a 18-bit bus switch or a 9-bit bus  
exchanger, which allows data exchange between the four  
signal ports via the data-select terminals.

Note 1: The Absolute Maximum Ratingsare 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 Conditionstable 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.

Note 6: 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).
