产品

概览

MM74HC240 3态缓冲器采用先进的硅栅极CMOS技术。 它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。 这些电路速度堪比低功耗肖特基器件，同时又能维持CMOS电路的优势，如高抗扰度和低功耗等。 该器件具有15个LS-TTL等效输入的扇出。 MM74HC240是一款反相缓冲器，具有两个低电平有效使能引脚（1G#和2G#）。 每个使能引脚可独立控制4个缓冲器。 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。

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

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.)
