概览

MM74HC125 和 MM74HC126 是通用型 3 态高速非反相缓冲器，采用先进的硅门极 CMOS 工艺。它们具有高驱动电流输出，即使在驱动大总线电容时也能实现高速运行。此类电路具有 CMOS 电路的低功耗，但与低功耗肖特基 TTL 电路相比仍然具有高速度。两个电路均能驱动最多 15 个低功耗肖特基输入。MM74HC125 需要采用 3 态控制输入 C 高电平才能将输出置于高阻抗状态，而 MM74HC126 需要该控制输入为低电平才能将输出置于高阻抗状态。通过对二极管联接 VCC 和接地，防止所有输入因静电放电受损。

  • This product is general usage and suitable for many different applications.

  • 典型传播延迟： 13 ns

Re-calculate Data

Data is based on the following assumptions.

Note: The temperature and confidence level may be adjusted to your requirements.

Disclaimer: A reliability FIT rate calculated using this tool shall not be used for any functional safety purpose. In case a raw FIT rate needs to be estimated for a component which is targeted to be used in a safety critical application (i.e. compliant to ISO 26262 standard) it should be calculated according to generic safety standards (IEC62380, IEC61709, SN29500, FIDES, etc.)
