FST34170MTD数据手册集成电路（IC）的信号开关多路复用器解码器规格书PDF

描述 Description

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 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 demultiplexes into B1 or B2 or both.
Two select (SEL1, SEL2) inputs provide switch enable control.

特性 Features

■ Slower Output Enable times prevent signal disruption
■ 4Ω 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

简介

FST34170MTD属于集成电路（IC）的信号开关多路复用器解码器。由制造生产的FST34170MTD信号开关，多路复用器，解码器逻辑型信号开关、多路复用器和编码器 IC 可用于对以数字格式表示数据的电信号进行路由和选择。这些器件与设计用于模拟信号的类似产品有所不同，它们保留的信息表示为两个电状态之一，而不是两个外部界限内的无穷变化量。
