描述 Description

The MC74AC540/74ACT540 and MC74AC541/74ACT541 are octal buffer/linedrivers designed to be employed as memory and address drivers, clock drivers andbus oriented transmitter/receivers. The MC74AC541/74ACT541 is a noninvertingoption of the MC74AC540/74ACT540. These devices are similar in function to the MC74AC240/74ACT240 andMC74AC244/74ACT244 while providing flow-through architecture (inputs on oppositeside from outputs). This pinout arrangement makes these devices especially usefulas output ports for microprocessors, allowing ease of layout and greater PC boarddensity.

簡(jiǎn)介

MC74AC540屬于集成電路（IC）的緩沖器驅(qū)動(dòng)器接收器收發(fā)器。由制造生產(chǎn)的MC74AC540緩沖器，驅(qū)動(dòng)器，接收器，收發(fā)器邏輯緩沖器、驅(qū)動(dòng)器、接收器和收發(fā)器允許隔離對(duì)某個(gè)電路的邏輯信號(hào)的訪問(wèn)，以用于另一電路。緩沖器將其輸入信號(hào)（不變或反相）傳遞到其輸出，并可能用于清除弱信號(hào)或驅(qū)動(dòng)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。
