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 B

or B

or
both.
Two select (SEL

, SEL

) inputs provide switch enable con-
trol.
