SN74ABT861DW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

SN74ABT861DW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SN74ABT861DW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

The ’ABT861 are 10-bit transceivers designed for

asynchronous communication between data

buses. The control-function implementation

allows for maximum flexibility in timing.

These devices allow noninverted data

transmission from the A bus to the B bus or from

the B bus to the A bus, depending on the logic

levels at the output-enable (OEAB and OEBA)

inputs.

When VCC is between 0 and 2.1 V, the device is

in the high-impedance state during power up or

power down. However, to ensure the

high-impedance state above 2.1 V, 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.

The SN54ABT861 is characterized for operation

over the full military temperature range of –55°C

to 125°C. The SN74ABT861 is characterized for

operation from –40°C to 85°C.
