概览

FXLH42245 是一款可配置的双电压供电转换器，适用于两个电压等级之间的双向电压转换。该器件实现了高达 3.6V 与低至 1.1V 之间的电压转换。A 端口跟踪 VCCA 电平，B 端口跟踪 VCCB 电平。两个端口均可接受 1.1V 至 3.6V 的电源电压等级。可在多种电压等级之间实现双向电压转换： 1.2V、1.5V、1.8V、2.5V 和 3.3V。该器件将保持 3 态，直到两个 VCC 均达到活动电平，让任一 VCC 能够首先通电。该器件也包含电源关闭控制电路，如果任一 VCC 移除，则会将器件置于 3 态。发射/接收 (T/R) 输入决定了数据流经该器件的方向。OE 输入处于高电平时则会将 A 和 B 端口同时置于 3 态状态，从而将两者禁用。FXLH42245 设计具备 VCCA 提供的控制引脚 (T/R 和 OE)。

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

  • 从1.1V到3.6V两个电平之间的双向接口
  • 完全可配置的输入跟踪VCC电平
  • 非优先上电；任一VCC都可能首先上电
  • 输出保持在3态状态，直到达到有效VCC电平
  • 如果任一VCC处于GND状态，则输出将会切换至3态
  • 数据输入上的总线保持功能消除了对外部上拉/下拉电阻的需要
  • B端口上的26W输出串联电阻可降低线路噪声
  • 断电保护
  • 控制输入(T/R，OE)电平参考VCCA电压
  • 24引脚MLP封装
  • ESD保护超过
  • - 4kV人体模型（根据JESD22-A114和Mil Std 883e 3015.7标准）
  • - 8kV人体模型I/O至GND（根据JESD22-A114和Mil Std 883e 3015.7标准）
  • - 1kV充电器件模型（根据ESD STM 5.3标准）
  • - 200V机械模型（根据JESD22-A115和ESD STM5.2标准）
