3 Description

These octal buffers and line drivers are designed

specifically to improve both the performance

and density of 3-state memory address drivers,

clockdrivers, and bus-oriented receivers and

transmitters. The SNx4HCT244 devices are organized

as two 4-bit buffers or drivers with separate outputenable

(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.

SN74HCT244PWE4屬于集成電路（IC） > 緩沖器，驅動器，接收器，收發(fā)器。美國德州儀器公司制造生產(chǎn)的SN74HCT244PWE4緩沖器，驅動器，接收器，收發(fā)器邏輯緩沖器、驅動器、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。
