概览

MC74AC245/74ACT245 包含八个带有 3 态输出的非反相双向缓冲器， 适用于总线导向型应用。汲电流能力在 A 和 B 端口 均为 24 mA。发射/接收 (T/Rbar) 输入 决定了数据流经双向收发器的方向。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 端口置于高电平 Z 状态，从而将两者禁用。

  • Noninverting Buffers
  • Bidirectional Data Path
  • A and B Outputs Source/Sink 24 mA
  • ACT245 Has TTL Compatible Inputs
  • Pb-Free Packages are Available

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.)
