74VHCT541A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

74VHCT541A屬于集成電路（IC）的緩沖器驅(qū)動器接收器收發(fā)器。由意法半導(dǎo)體集團制造生產(chǎn)的74VHCT541A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)總線之間進行隔離通信。
