VCX163245 是一款双电源 16 位转换收发器,通过提供真实信号转换,在不同电源电压下,实现总线间的双向异步通信。电源轨包括 VCCA 和 VCCB,前者为更高电势轨,在 2.3V 至 3.6V 范围内运行,后者为更低电势轨,在 1.65V 至 2.7V 范围内运行。(VCCB 必须小于或等于 VCCA 才能实现正确的器件运行。)此双电源设计允许从 1.8V 至 2.5V 总线转换为最高 3.3V 的更高电势的总线。发射/接收 (T/R#) 输入决定了数据流向。发射(有效高电平)让数据能够从 A 端口流向 B 端口;接收(有效低电平)则让数据能够从 B 端口流向 A 端口。输出启用 (OE#) 输入如果为高电平,则会将 A 端口和 B 端口置于高阻抗状态,从而将两者禁用。A 端口与更高电压总线 (2.7V - 3.3V) 连接;B 端口与更低电压总线 (1.8V - 2.5V) 连接。VCX163245 的设计还使得控制引脚 (T/R#n, OE#n) 由 VCCB 供电。74VCX163245 适用于混合电压应用,如使用 1.8V CPU 和 3.3V 外围部件的笔记本电脑。它采用先进的 CMOS 工艺,在保持 CMOS 低功耗的同时,实现了高速运行。

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.)
