FST16210
20-Bit Bus Switch
General Description
Features
The Fairchild Switch FST16210 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.
■ 4 switch 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 is organized as a 10-bit or 20-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.

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.

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).
