SN74ABT162244DGVR集成电路（IC）的缓冲器驱动器接收器收发器规格书PDF中文资料

SN74ABT162244DGVR属于集成电路（IC）的缓冲器驱动器接收器收发器。由德州仪器制造生产的SN74ABT162244DGVR缓冲器，驱动器，接收器，收发器逻辑缓冲器、驱动器、接收器和收发器允许隔离对某个电路的逻辑信号的访问，以用于另一电路。缓冲器将其输入信号（不变或反相）传递到其输出，并可能用于清除弱信号或驱动负载。在布尔逻辑仿真器中，缓冲器主要用于增加传播延迟。逻辑接收器和收发器允许在数据总线之间进行隔离通信。

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.
