概览

LVX4245 是一种双电源、8 位转换收发器，适用于 5V/3V 混合电源环境中 3V 总线和 5V 总线之间的接口。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 端口连接 5V 总线；B 端口连接 3V 总线。LVX4245 适用于混合电压应用，如使用 3.3V CPU 和 5V LCD 显示器的膝上型电脑。

  • This product is general usage and suitable for many different applications.

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.)
