产品型号SN74AHC1G125DCKR的概述

芯片SN74AHC1G125DCKR的概述 SN74AHC1G125DCKR是一款由德州仪器（Texas Instruments，TI）生产的单通道缓冲器/驱动器，采用AHC系列技术。这款芯片在数字电路设计中广泛应用，因为其具备高性能和低功耗的特点。它提供了一个高电平有效的输出信号，当输入高电平时，输出也为高电平，而输入为低电平时，输出为低电平。此外，该芯片还具备3-state输出功能，适合于多路复用或数据总线的应用场景。芯片SN74AHC1G125DCKR的详细参数 SN74AHC1G125DCKR的核心性能参数包括： - 电源电压（Vcc）：2.0V至5.5V，适应不同的电源环境。 - 输入电压（Vi）：最高能适应Vcc范围内的电压。 - 输出电压（Vo）：当为高电平时，输出接近Vcc；低电平输出接近地。 - 逻辑电流（I）：通常工作在微安级，具体取决于负载及工作条件。 - 输入...

description/ordering information

The SN74AHC1G125 is a single bus buffer gate/line driver with 3-state output. The output is disabled when the

output-enable (OE) input is high. When OE is low, true data is passed from the A input to the Y output.

To ensure the high-impedance state during power up or power down, OE should be tied to V through a pullup

resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.

Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and

functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not

implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

NOTES: 1. The input and output voltage ratings may be exceeded if the input and output current ratings are observed.

2. The package thermal impedance is calculated in accordance with JESD 51-7.
