MM74HC125和MM74HC126是采用先进硅栅极CMOS技术的通用3态高速同相缓冲器。 它们具有高驱动电流输出,即使在驱动大型总线电容时也能实现高速运行。 此类电路具有低功耗CMOS电路,并且具有与低功耗肖特基TTL电路相媲美的速度。 两种电路都能驱动高达15个低功率肖特基输入。 MM74HC125要求3态控制输入C为高电平以将输入变为高阻抗条件,而MM74HC126要求控制输出为低电平以将输出变为高阻抗。 所有输入通过连接至VCC和接地的二极管加以保护,以免因静电放电而受损。

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.)
