MC14556BCP集成電路（IC）的信號開關多路復用器解碼器規(guī)格書PDF中文資料

MC14556BCP屬于集成電路（IC）的信號開關多路復用器解碼器。由安森美半導體公司制造生產的MC14556BCP信號開關，多路復用器，解碼器邏輯型信號開關、多路復用器和編碼器 IC 可用于對以數字格式表示數據的電信號進行路由和選擇。這些器件與設計用于模擬信號的類似產品有所不同，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的無窮變化量。

Dual Binary to 1?of?4 Decoder/Demultiplexer

The MC14555B and MC14556B are constructed with complementary MOS (CMOS) enhancement mode devices. Each Decoder/Demultiplexer has two select inputs (A and B), an active low Enable input (E), and four mutually exclusive outputs (Q0, Q1, Q2, Q3). The MC14555B has the selected output go to the “high” state, and the MC14556B has the selected output go to the “l(fā)ow” state. Expanded decoding such as binary?to?hexadecimal (1?of?16), etc., can be achieved by using other MC14555B or MC14556B devices.
