概览

FXMA108 是一款可配置的栓电压供电转换器，适用于两个逻辑电平之间的单向和双向电压转换。该器件实现了高达 5.5V 与低至 1.65V 之间的电压转换。A 端口跟踪 VCCA 电平，B 端口跟踪 VCCB 电平。可在多种电压等级之间实现双向电压转换： 1.8V、2.5V、3.3V 和 5.0V。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。如果任一 VCC 移除，内部电源关闭控制电路则会将器件置于 3 态。/OE 输入处于高电平时则会将 A 侧和 B 侧同时置于高阻抗状态，从而将两者禁用。/OE 输入由 VCCA 提供。FXMA108 支持双向转换，且无需方向控制引脚。该器件的两侧均具有自动方向感应功能。任一端口均可感应输入信号，并将其作为输出信号传输到另一个端口。

  • This product is general usage and suitable for many different applications.
  • 从1.65V到5.5V两个电平之间的双向接口
  • 完全可配置： 输入和输出跟踪VCC
  • 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
  • 断电保护
  • 数据输入上的总线保持无需上拉电阻
  • 参考VCCA的控制输入(/OE)
  • 20引脚DQFN封装
  • 不需要方向控制
  • 当在2.5V和5.0V间转换时，吞吐率为80Mbps
  • ESD保护超过：
  • - 8kV人体模型（B端口I/O至GND）（JESD22-A114；Mil Std 883e 3015.7）
  • - 5kV人体模型（A端口I/O至GND）（JESD22-A114；Mil Std 883e 3015.7）
  • 2kV带电器件模型(ESD STM 5.3) (JESD22-C101)
