74HCT154PW屬于集成電路（IC）的信號開關(guān)多路復(fù)用器解碼器。由安世半導(dǎo)體(中國)有限公司制造生產(chǎn)的74HCT154PW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。

1. General description

The 74HC154; 74HCT154 is a 4-to-16 line decoder/demultiplexer. It decodes four binary weighted

address inputs (A0 to A3) to sixteen mutually exclusive outputs (Y0 to Y15). The device features

two input enable (E0 and E1) inputs. A HIGH on either of the input enables forces the outputs

HIGH. The device can be used as a 1-to-16 demultiplexer by using one of the enable inputs as

the multiplexed data input. When the other enable input is LOW the addressed output will follow

the state of the applied data. Inputs include clamp diodes. This enables the use of current limiting

resistors to interface inputs to voltages in excess of VCC.
