MM74HC244 是一款非反相缓冲器,具有两个有效低电平启用(1G 和 2G),每个启用单独控制 4 个缓冲器。此器件没有施密特触发器输入。这些 3 态缓冲器采用先进的硅门极 CMOS 技术,属于通用型高速非反相缓冲器。它们具有高驱动电流输出,即使驱动大型总线电容,也可实现高速运行。这些电路的速度可与低功率肖特基器件相媲美,同时保留了 CMOS 电路的优势,即抗扰性强,功耗低。这三种器件都有 15 个 LS-TTL 等效输入的扇出。通过将二极管箝位到 VCC 和接地,可防止所有输入因静电放电而受损。

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.)
