SN74ACT244NSRG4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

SN74ACT244NSRG4屬于集成電路（IC）的緩沖器驅(qū)動器接收器收發(fā)器。由德州儀器制造生產(chǎn)的SN74ACT244NSRG4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。

3 Description

These SNx4ACT244 octal buffers and drivers are

designed specifically to improve the performance and

density of 3-state memory address drivers, clock

drivers, and bus-oriented receivers and transmitters.

The SNx4ACT244 devices are organized as two 4-

bit buffers and drivers with separate output-enable

(OE) inputs. When OE is low, the device passes noninverted

data from the A inputs to the Y outputs.

When OE is high, the outputs are in the highimpedance

state.
