概览

MC14503B 是一款六路非反相缓冲器，带 3 态输出、高电流源汲能力。3 态输出可用于公共总线应用。提供两个禁用控制。禁用 A 输入上的高电平将导致缓冲区 1 到 4 的输出进入高阻抗状态，禁用 B 输入上的高电平将导致缓冲区 5 和 6 进入高阻抗状态。

  • 3-State Outputs
  • TTL Compatible - Will Drive One TTL Load Over Full Temperature Range
  • Supply Voltage Range = 3.0 Vdc to 18 Vdc
  • Two Disable Controls for Added Versatility
  • Pin for Pin Replacement for MM80C97 and 340097
  • 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.)
