MC74LVX138DR2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

MC74LVX138DR2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MC74LVX138DR2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(gè)電狀態(tài)之一，而不是兩個(gè)外部界限內(nèi)的無窮變化量。

The MC74LVX138 is an advanced high speed CMOS 3?to?8 line decoder. The inputs tolerate voltages up to 7.0 V, allowing the interface of 5.0 V systems to 3.0 V systems.

When the device is enabled, three Binary Select inputs (A0 ? A2) determine which one of the outputs (O0 ? O7) will go Low. When enable input E3 is held Low or either E2 or E1 is held High, decoding function is inhibited and all outputs go high. E3, E2, and E1 inputs are provided to ease cascade connection and for use as an address decoder for memory systems.
