General Description
The Fairchild Switch FST32253 is a dual 4:1 high-speed CMOS TTL-compatible 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.

FEATUREs
■ 25Ω 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
