描述 Description

General Description
The 74F251A is a high-speed 8-input digital multiplexer. It provides, in one package, the ability to select one bit of data from up to eight sources. It can be used as a universal function generator to generate any logic function of four variables. Both assertion and negation outputs are provided.

特性 Features

■ Multifunctional capability
■ On-chip select logic decoding
■ Inverting and non-inverting 3-STATE outputs

简介

74F251A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74F251A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。
