SN74CBT3383DWR屬于集成電路（IC）的信號開關(guān)多路復用器解碼器。由美國德州儀器公司制造生產(chǎn)的SN74CBT3383DWR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。

3 Description

The SN74CBT3383 and SN54CBT3383 devices

provide ten bits of high-speed TTL-compatible

bus switching or exchanging. The low ON-state

resistance of the switch allows connections to be

made with minimal propagation delay.

The devices operate as a 10-bit bus switch or a

5-bit bus exchanger, which provides swapping of

the A and B pairs of signals. The bus-exchange

function is selected when BX is high. The

switches are connected when BE is low.
