VHCT138A 是一种先进的高速 CMOS 3-8 解码器,采用硅门极 CMOS 工艺制造。它实现了与同等双极肖特基 TTL 相似的高运行速度,同时保持了 CMOS 低功耗。启用该器件时,3 个二进制选择输入(A0、A1 和 A2)决定了哪个输出 (O#0-O#7) 将转至低电平。启用输入 E3 保持在低电平,或者 E#1 或 E#2 保持在高电平时,解码功能将被禁止,所有输出均转至高电平。E3、E#1 和 E#2 输入用于简化级联联接,并用作内存系统的地址解码器。保护电路可确保对输入引脚应用 0V 到 7V 电压而无需考虑 VCC = 0V 时的电源电压和输出引脚。这些电路可防止器件由于不匹配的供电和输入/输出电压而损坏。此器件可用作 3V 系统与 5V 系统以及两种电源系统的接口,如备用电池。

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.)
