Description

The Fairchild Switch FST34170 is a 17-bit to 34-bit highspeed 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.

The FST34170 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 control.
