概览

MM74HC373 高速八路 D 型锁存利用先进的硅门极 CMOS 工艺。此器件具有标准 CMOS 集成电路的高抗扰性和低功耗，还具有驱动 15 个 LS-TTL 负载的能力。由于其大输出驱动能力和 3 态特性，此类器件适用于接口总线组织系统中的总线线路。当锁存启用输入为高电平时，Q 输出将跟随 D 输入。当锁存启用变为低电平时，D 输入端的数据将保留在输出端，直至锁存器启用再次变为高电平。如对输出控制输入应用高逻辑电平，所有输出将进入高阻抗状态，无论其他输入端存在什么信号以及存储元件的状态如何。74HC 逻辑系列与标准 74LS 逻辑系列在速度、功能和引脚输出方面均兼容。通过箝位到 VCC 和接地的内部二极管，可针对由于静电荷导致的损坏保护所有输入。

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.)
