SN74HCT645PW屬于集成電路（IC）的緩沖器驅動器接收器收發(fā)器。由美國德州儀器公司制造生產的SN74HCT645PW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)器允許在數據總線之間進行隔離通信。

description/ordering information

These octal bus transceivers are designed for asynchronous two-way communication between data buses.

These devices transmit data from the A bus to the B bus or from the B bus to the A bus, depending upon the

level at the direction-control (DIR) input. The output-enable (OE) input can be used to disable the device so the

buses are effectively isolated.
