NVT2001; NVT2002: 适用于开漏和推挽应用的双向电压电平变换器

NVT2001/02是双向电压电平变换器,工作范围为1.0 V至3.6 V (Vref(A))和1.8 V至5.5 V (Vref(B)),允许在开漏或推挽应用中进行1.0 V和5 V之间的双向电压变换而无需方向引脚。对于具有50 pF电容和197 Ω上拉的开漏系统,为传输速度< 33 MHz的电平变换应用提供1位或2位的位宽。

当An或Bn端口为低电平时,钳位处于通态且An和Bn端口之间存在低电阻连接。开关的低通态电阻(Ron)允许以最小传输延迟建立连接。假设Bn端口上为更高的电压,当Bn端口为高电平时,An端口上的电压限制为通过VREFA设置的电压。当An端口为高电平时,上拉电阻会将Bn端口上拉至漏极上拉供电电压(Vpu(D))。此功能允许在用户选择的更高和更低电压之间进行无缝变换,而无需方向控制。

当EN为高电平时,变换器开关打开,且An I/O分别连接至Bn I/O,允许端口之间的双向数据流动。当EN为低电平时,变换器开关关闭,且端口之间存在高阻抗状态。EN输入电路是由Vref(B)供电。为确保上电或掉电时的高阻抗状态,EN必须为低电平。

所有通道具有相同的电特性,输出间的电压或传输延迟具有最小的偏差。由于开关是对称制造的,所以这有利于分离式晶体管电压变换解决方案。变换器为低电压器件提供极佳的ESD保护并同时保护低ESD抗性器件。
