概览

MC14585B 4 位幅度比较器由互补 MOS (CMOS) 增强模式器件构成。该电路具有八个比较输入（A3，B3，A2，B2，A1，B1，A0，B0）、三个级联输入（A B）和三个输出（A B）。该器件比较两个 4 位字（A 和 B），并在适当输出上按高级别确定它们是“小于”、“等于”还是“大于”。对于大于 4 位的字，单元级联可以通过将输出 (A > B)、(A < B) 和 (A = B) 连接到下一个有效比较器的相应输入来完成。最低有效（第一）比较器上的输入 (A < B)、(A = B) 和 (A > B) 分别连接到低、高和低电平。应用包括 CPU 的逻辑、仪器条件的校正和/或检测、测试仪中的比较器、转换器和控件。

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.)
