SN74ABT162244DL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SN74ABT162244DL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/ordering information

The ’ABT162244 devices are 16-bit buffers and

line drivers designed specifically to improve both

the performance and density of 3-state memory

address drivers, clock drivers, and bus-oriented

receivers and transmitters. These devices can be

used as four 4-bit buffers, two 8-bit buffers, or one

16-bit buffer. These devices provide noninverting

outputs and symmetrical active-low

output-enable (OE) inputs.

The outputs, which are designed to source or sink up to 12 mA, include equivalent 25-Ω series resistors to

reduce overshoot and undershoot.

To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pullup

resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
