74AC11245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74AC11245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。

description

This octal bus transceiver is designed for asynchronous two-way communication between data buses. The

control-function implementation minimizes external timing requirements.

The device allows noninverted data transmission from the A bus to the B bus or from the B bus to the A bus,

depending on the logic level at the direction-control (DIR) input. The output-enable (OE) input can be used to

disable the device so that the buses are effectively isolated.

The 74AC11245 is characterized for operation from –40°C to 85°C.
