MC74LVX139M集成電路（IC）的信號(hào)開關(guān)多路復(fù)用器解碼器規(guī)格書PDF中文資料

MC74LVX139M屬于集成電路（IC）的信號(hào)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MC74LVX139M信號(hào)開關(guān)，多路復(fù)用器，解碼器邏輯型信號(hào)開關(guān)、多路復(fù)用器和編碼器 IC 可用于對(duì)以數(shù)字格式表示數(shù)據(jù)的電信號(hào)進(jìn)行路由和選擇。這些器件與設(shè)計(jì)用于模擬信號(hào)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。

Dual 2-to-4 Decoder/Demultiplexer

The MC74LVX139 is an advanced high speed CMOS 2?to?4 decoder/ demultiplexer fabricated with silicon gate CMOS technology.

When the device is enabled (E = low), it can be used for gating or as a data input for demultiplexing operations. When the enable input is held high, all four outputs are fixed high, independent of other inputs.

The inputs tolerate voltages up to 7.0 V, allowing the interface of 5.0 V systems to 3.0 V systems.
