MM74HC74A 采用先进的 CMOS 工艺制造,运行速度与 LS-TTL 零部件相媲美。它具有标准 CMOS 集成电路的高抗扰度和低功耗,并能驱动 10 个 LS-TTL 负载。此触发器拥有独立的数据、预设、清除和时钟输入,以及 Q 和 Q# 输出。时钟脉冲正向转换期间,数据输入端的逻辑电平被传送至输出。预设和清除输入与时钟无关,通过适当输入端的低电平来完成。74HC 逻辑系列与标准 74LS 逻辑系列在功能和引脚输出方面兼容。通过将内部二极管箝位到 VCC 和接地,防止所有输入因静电放电受损。

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.)
