3 Description

The SN74LV138A-Q1 device is 3-line to 8-line

decoders/demultiplexers designed for 2 V to 5.5 V

VCC operation.

The conditions at the binary-select inputs (A0, A1, A2)

and the three enable inputs (G2, G0, G1) select one

of eight output lines. The two active-low (G0, G1) and

one active-high (G2) enable inputs reduce the need

for external gates or inverters when expanding.

SN74LV138A屬于集成電路（IC） > 信號開關(guān)，多路復用器，解碼器。美國德州儀器公司制造生產(chǎn)的SN74LV138A信號開關(guān)，多路復用器，解碼器邏輯型信號開關(guān)、多路復用器和編碼器 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。
