SN74AVC16244DGVR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

SN74AVC16244DGVR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SN74AVC16244DGVR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

A Dynamic Output Control (DOC) circuit is implemented, which, during the transition, initially lowers the output

impedance to effectively drive the load and, subsequently, raises the impedance to reduce noise. Figure 1 shows

typical VOL vs IOL and VOH vs IOH curves to illustrate the output impedance and drive capability of the circuit. At

the beginning of the signal transition, the DOC circuit provides a maximum dynamic drive that is equivalent to a

high-drive standard-output device. For more information, refer to the TI application reports, AVC Logic Family
