概览

LCXH245 包含八个带有 3 态输出的非反向双向缓冲器，适用于总线导向型应用。此器件适用于低电压（2.5V 和 3.3V）VCC 应用。T/R# 输入决定了数据流经该器件的方向。OE# 输入将 A 和 B 端口置于高阻抗状态，从而将两者禁用。LCXH245 采用先进的 CMOS 工艺，在保持 CMOS 低功耗的同时，实现了高速运行。LCXH16244 数据输入包括有源总线保持电路，无需外部上拉电阻将未使用或浮动的数据输入保持在有效逻辑电平。

  • This product is general usage and suitable for many different applications.
  • 5V容差控制输入
  • 提供2.3V-3.6V VCC规格
  • 7.0 ns tPD最大值(VCC = 3.3V)，10 µA ICC最大值
  • 关断高阻抗输入
  • ±24 mA输出驱动(VCC = 3.0V)
  • 实施专利噪声/电磁干扰(EMI)消减电路
  • 闩锁性能超过500 mA
  • 输入端总线保持功能避免了外部上拉/下拉电阻的需要。
