FST34170
17-Bit to 34-Bit Multiplexer/Demultiplexer Bus Switch
General Description
The Fairchild Switch FST34170 is a 17-bit to 34-bit 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 propaga-
tion delay or generating additional ground bounce noise.
The device can be used in applications where two buses
need to be addressed simultaneously. The FST34170 is
designed so that the A Port demultiplexes into B₁ or B₂ or
both.
Two select (SEL₁, SEL₂) inputs provide switch enable con-
trol.
Features
■ Slower Output Enable times prevent signal disruption
: ■ 4 switch connection between two ports
■ Minimal propagation delay through the switch
■ Low l_CC
■ Zero bounce in flow-through mode
■ Control inputs compatible with TTL level
■ See Applications Note AN-5008 for details
