SN74HCT244屬于集成電路（IC）的緩沖器驅(qū)動器接收器收發(fā)器。由美國德州儀器公司制造生產(chǎn)的SN74HCT244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。

description/ordering information

This octal buffer and line driver is designed specifically to improve both the performance and density of 3-state

memory address drivers, clock drivers, and bus-oriented receivers and transmitters. The SN74HCT244 device

is organized as two 4-bit buffers/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

high-impedance state.
