MC14028B集成電路（IC）的信號開關(guān)多路復(fù)用器解碼器規(guī)格書PDF中文資料

MC14028B屬于集成電路（IC）的信號開關(guān)多路復(fù)用器解碼器。由安森美半導(dǎo)體公司制造生產(chǎn)的MC14028B信號開關(guān)，多路復(fù)用器，解碼器邏輯型信號開關(guān)、多路復(fù)用器和編碼器 IC 可用于對以數(shù)字格式表示數(shù)據(jù)的電信號進(jìn)行路由和選擇。這些器件與設(shè)計(jì)用于模擬信號的類似產(chǎn)品有所不同，它們保留的信息表示為兩個電狀態(tài)之一，而不是兩個外部界限內(nèi)的無窮變化量。

The MC14028B decoder is constructed so that an 8421 BCD code on the four inputs provides a decimal (one?of?ten) decoded output, while a 3?bit binary input provides a decoded octal (one?of?eight) code output with D forced to a logic “0”. Expanded decoding such as binary?to?hexadecimal (one?of?sixteen), etc., can be achieved by using other MC14028B devices. The part is useful for code conversion, address decoding, memory selection control, demultiplexing, or readout decoding.
