圣邦微（SGMICRO）的SGM4574芯片是一款四位双向电平转换芯片，它不需要方向控制信号，支持两种输出方式，开漏与推挽，两种输出方式对应着不同的转换速率，开漏输出可达到最大2Mbps的rate sheet，而推挽输出可以达到24Mbps。本文主要介绍了双向电平转换芯片SGM4574在设计过程中的一些注意事项与设计经验，给大家在设计中一些参考。

以下是它的典型设计应用图：

该芯片的A端口支持1.65~5.5V的电压输入，B端口支持2.3V~5.5V的电压输入，芯片内部集成了10K的上拉电阻，通常用于开漏输出，不过此芯片也可以用于CMOS的推挽输出应用。而在应用过程中始终要保持VCCA≤VCCB，不过在上电的过程中VCCA可以≥VCCB，这不会损坏芯片，芯片有一个OE口，此引脚相当于使能引脚，对此引脚进行低电平输入的操作会使整个芯片处于高阻抗状态。

在此芯片的设计过程中，转换速率也是非常重要的一个性能指标，AB端口不同的供电对应着不同的转换速率，大家可参考下图：

同时，如果在设计中想要改变输出电压的水平，可以在外部外接上下拉电阻。外接上拉电阻可以使得VOL抬升，外接下拉电阻会使得输出的VOH下降，此举对输出的负面影响较大，所以也建议在使用的过程中最好用于高阻抗负载，高阻抗负载对此影响比较小。

【经验】基于双向电压电平转换器SGM4556解决渗漏检测仪5V转3.3V数据传输问题

笔者参与渗漏检测仪的项目设计，需要使用E931.96芯片进行人体的检测，但是由于笔者使用的是5v的单片机，而E931.96使用电压为3.3V，根据资料5v的单片机需要对3.3V的芯片写指令已完成某些功能。因此需要将5V的数据转换为3.3V。了解到世强代理的圣邦微电子有一款专门用于双向电压电平转换器，可以应用于不同电压等级芯片之间的数据传输，数据传输速度最高可达100Mbps。

【经验】外部上拉和下拉电阻如何影响自动双向电平转换芯片RS010x和RS020x的VOL和VOH电平？

RS010x和RS020x自动双向电平转换芯片是润石科技推出的自动双向电平转换芯片，因RS010x内部有上拉电阻、RS020x内部有串联电阻，使这两款器件对外部上拉或下拉电阻相对敏感。
