概览

MC74LCX374 是一款高性能、非反相八路 D 型触发器，由 2.3 至 3.6V 电源供电。高阻抗 TTL 兼容输入可明显降低输入驱动器的电流负载，而 TTL 兼容输出改善了开关噪声性能。5.5V 的 VI 规格，因而 MC74LCX374 输入可由 5V 器件安全驱动。MC74LCX374 由 8 个边触发触发器组成，它们有各自的 D 型输入和 3 态实输出。缓冲时钟和缓冲输出启用 (OEbar) 对于所有触发器是公共的。八个触发器将存储各个 D 输入的状态，以满足设置要求和保持低-高电平时钟 (CP) 转换的时间要求。当 OEbar 为低电平时，输出会提供八个触发器的内容。当 OEbar 为高电平时，输出进入高阻抗状态。OEbar 输入电平不会影响触发器的运行。

  • Designed for 2.3 to 3.6V VCC Operation
  • 5V Tolerant - Interface Capability With 5V TTL Logic
  • Supports Live Insertion and Withdrawal

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.)
