MC74AC646集成電路（IC）的緩沖器驅(qū)動器接收器收發(fā)器規(guī)格書PDF中文資料

MC74AC646屬于集成電路（IC）的緩沖器驅(qū)動器接收器收發(fā)器。由安森美半導(dǎo)體公司制造生產(chǎn)的MC74AC646緩沖器，驅(qū)動器，接收器，收發(fā)器邏輯緩沖器、驅(qū)動器、接收器和收發(fā)器允許隔離對某個電路的邏輯信號的訪問，以用于另一電路。緩沖器將其輸入信號（不變或反相）傳遞到其輸出，并可能用于清除弱信號或驅(qū)動負(fù)載。在布爾邏輯仿真器中，緩沖器主要用于增加傳播延遲。邏輯接收器和收發(fā)器允許在數(shù)據(jù)總線之間進(jìn)行隔離通信。

Octal Transceiver/Register with 3-State Outputs (Non-inverting)

The MC74AC646/74ACT646 consist of registered bus transceiver circuits, with outputs, D?type flip?flops and control circuitry providing multiplexed transmission of data directly from the input bus or from the internal storage registers. Data on the A or B bus will be loaded into the respective registers on the LOW?to?HIGH transition of the appropriate clock pin (CAB or CBA). The four fundamental data handling functions available are illustrated Figures 1 to 4.

? Independent Registers for A and B Buses

? Multiplexed Real?Time and Stored Data Transfers

? Choice of True and Inverting Data Paths

? 3?State Outputs

? 300 mil Slim Dual In?Line Package

? Outputs Source/Sink 24 mA

? ′ACT646 Has TTL Compatible Inputs
