SN74LS244NSRG4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

SN74LS244NSRG4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SN74LS244NSRG4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。

3 Description

The SNx4LS24x, SNx4S24x octal buffers and line

drivers are designed specifically to improve both the

performance and density of three-state memory

address drivers, clock drivers, and bus-oriented

receivers and transmitters. The designer has a choice

of selected combinations of inverting and noninverting

outputs, symmetrical, active-low outputcontrol

(G) inputs, and complementary output-control

(G and G) inputs. These devices feature high fan-out,

improved fan-in, and 400-mV noise margin. The

SN74LS24x and SN74S24x devices can be used to

drive terminated lines down to 133 Ω.
