FST16232
Synchronous 16-Bit to 32-Bit
Multiplexer/Demultiplexer Bus Switch
General Description
The Fairchild Switch FST16232 is a 16-bit to 32-bit high-
speed CMOS TTL-compatible synchronous multiplexer/
demultiplexer bus switch. 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 allows two separate datapaths to be multi-
plexed onto, or demultiplexed from, a single path. Two con-
trol select pins (S₁, S₀) are synchronous and clocked on
the rising edge of CLK when CLKEN is LOW.
Features
s 4Ω switch connection between two ports.
s Minimal propagation delay through the switch.
s Low l_CC.
s Zero bounce in flow-through mode.
s Control inputs compatible with TTL level.
