Texas Instruments LSF0204x 双向多电压电平转换器

德州仪器 LSF0204x 双向多电压电平转换器是一款双向电压电平转换器，工作在 1.0V 到 4.5V （Vref_A） 和 1.8V 到 5.5V （Vref_B）的范围内。可在开漏或推挽应用中实现 1.0V 至 5.0V 的双向电压转换，无需使用方向端子。对于采用 15pF 电容器和 165Ω 上拉电阻的开漏系统，LSF0204x 可进行传输速度大于 100MHz 的电平转换。

特性

  • Provides bi-directional voltage translation with no direction terminal
  • Less than 1.5ns maximum propagation delay
  • Supports high-speed translation, greater than 100MHz
  • Supports Ioff, partial power down mode
  • Allows bi-directional voltage level translation between:
    • 0.8 V ↔ 1.8/2.5/3.3/5V
    • 1.2 V ↔ 1.8/2.5/3.3/5V
    • 1.8 V ↔ 2.5/3.3/5V
    • 2.5 V ↔ 3.3/5V
    • 3.3 V ↔ 5V
