概览

LVT2244和LVTH2244均为八路缓冲器和线路驱动器，设计用作存储器地址驱动器、时钟驱动器以及可提高印刷电路板密度的总线式发射器或接收器。 等效25ohm串联电阻用于减少输出过冲和欠冲。 LVTH2244数据输入具有总线保持特性，无需外部上拉电阻来保持未使用的输入端。 这些缓冲器和线路驱动器设计用于低电压(3.3V) VCC应用，但也可向5V环境提供TTL接口。 LVT2244和LVTH2244采用先进的BiCMOS技术制造，以实现高速运行（类似于5V ABT），同时保持低功耗。

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

  • 系统在5V VCC时的输入和输出接口能力
  • 输出上的等效25ohm串联电阻
  • 采用总线保持数据输入，无需外部上拉电阻来保持未使用的输入端(74LVTH2244)，同时也提供无总线保持特性的版本(74LVT2244)
  • 允许带电插/拔
  • 上电/掉电高阻抗提供无干扰总线负载
  • -12 mA/+12 mA输出源电流/灌电流
  • 闩锁性能超过500 mA
  • 静电放电(ESD)性能：人体模型> 2000V机械模型> 200V充电器件模型> 1000V

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.)
