概览

AC/ACT245包含八个具有3态输出的同相双向缓冲器，用于总线导向应用。 A端和B端的灌电流能力皆为24 mA。 传输/接收(T/R#)输入决定数据在双向收发器中流动的方向。 发射（高电平有效）让数据从A端口流到B端口；接收（低电平有效）让数据从B端口流到A端口。 输出使能输入为高电平时，可通过将A和B端口置于高阻抗状态来停用它们。

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

  • ICC和IOZ降低50%
  • 同相缓冲器
  • 双向数据路径
  • A和B输出供给/吸收24 mA
  • ACT245具有TTL兼容输入

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.)
