74AUC1G125DBVRG4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

74AUC1G125DBVRG4属于集成电路（IC）的缓冲器驱动器接收器收发器。由美国德州仪器公司制造生产的74AUC1G125DBVRG4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。

3 Description

The SN74AUC1G125 device is a single line driver

with a 3-state output. The output is disabled when the

output-enable (OE) input is high.

The AUC logic family is specifically designed for

speed and is optimized for operation between 1.65-V

and 1.95-V VCC. With an optimal supply and 15-pF

load the device can operate at over 250 MHz, or

500 Mbps. The unique output structure of the AUC

family provides great signal integrity without the need

for external termination when driving 50- to 65-Ω

transmission lines of moderate length (less than 15

cm). See Application of the Texas Instruments AUC

Sub-1-V Little Logic Devices for more details on this

technology.

This device is available in the popular SOT-23 and

SC70 packages, as well as the advanced NanoFree™

DSBGA package. NanoFree™ package technology is

a major breakthrough in IC packaging concepts, using

the die as the package.
