概览

MC74HC238A 与 LS238 的引脚输出相同。该器件输入与标准 CMOS 输出兼容；带有上拉电阻，它们与 LSTTL 输出兼容。HC238A 将三位地址解码为八分之一有效高电平输出。此器件具有三个芯片选择输入、两个有效低电平和一个有效高电平，可实现信号分离、级联和芯片选择功能。信号分离功能通过使用地址输入来选择所需器件输出而实现；一个芯片选择用作数据输入，其他芯片选择保持为激活状态。

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.)
