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 lCC

■ Zero bounce in flow-through mode

■ Control inputs compatible with TTL level

■ See Applications Note AN-5008 for details
