SN74LV244ADWR集成電路（IC）的緩沖器驅(qū)動(dòng)器接收器收發(fā)器規(guī)格書PDF中文資料

SN74LV244ADWR屬于集成電路（IC）的緩沖器驅(qū)動(dòng)器接收器收發(fā)器。由德州儀器制造生產(chǎn)的SN74LV244ADWR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。

3 Description

The SN74LV244A octal buffers and line drivers are

designed for 2-V to 5.5-V VCC operation.

The SN74LV244A devices are designed specifically

to improve both performance and density of the 3-

state memory address drivers, clock drivers, and busoriented

receivers and transmitters. These devices

are organized as two 4-bit line drivers with separate

output-enable (OE) inputs.
