3 Description

The SNx4HCT245 octal bus transceivers

are designed for asynchronous two-way

communication between data buses. The controlfunction

implementation minimizes external timing

requirements.

The SNx4HCT245 devices allow data transmission

from the A bus to the B bus or from the B bus to the

A bus, depending upon the logic level at the directioncontrol

(DIR) input. The output-enable ( OE) input can

be used to disable the device so that the buses are

effectively isolated.

SN74HCT245DWRG4屬于集成電路（IC） > 緩沖器，驅(qū)動(dòng)器，接收器，收發(fā)器。美國(guó)德州儀器公司制造生產(chǎn)的SN74HCT245DWRG4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。
