FST34170
17-Bit to 34-Bit Multiplexer/Demultiplexer Bus Switch

General Description

The FST34170 Fairchild switch is a 17-bit to 34-bit, high-speed, CMOS TTL-compatible multiplexer / de-multiplexer 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 device can be used in applications where two buses need to be addressed simultaneously. The FST34170 is designed so that the A port de-multiplexes into B1 or B2 or both. Two select (SEL₁, SEL₂) inputs provide switch enable control.

Features

Slower Output Enable Times Prevent Signal Disruption
4W 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
