FST33X257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 FST33X257 is a 24:12 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.
When OE x is LOW, the select pin connects the A Port to the selected B Port output. When OEx is HIGH, the switch is OPEN and a high-impedance state exists between the two ports.

特性 Features

■ 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

简介

FST33X257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FST33X257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。
