74ALVCH16244DLG4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

74ALVCH16244DLG4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74ALVCH16244DLG4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

This 16-bit buffer/driver is designed for 1.65-V to

3.6-V VCC operation.

The SN74ALVCH16244 is designed specifically to

improve the performance and density of 3-state

memory address drivers, clock drivers, and

bus-oriented receivers and transmitters.

The device can be used as four 4-bit buffers, two

8-bit buffers, or one 16-bit buffer. It provides true

outputs and symmetrical active-low output-enable

(OE) inputs.

To ensure the high-impedance state during power up

or power down, OE should be tied to VCC through a blank

pullup resistor; the minimum value of the resistor is

determined by the current-sinking capability of the blank

driver. blank
