RS485驱动芯片SN65HVD1781的ESD问题

Other Parts Discussed in Thread: SN65HVD1781

1、请问SN65HVD1781的PIN6【A】、PIN7【B】是否内置了TVS?

2、如果是内置TVS,规格是如何?(VRWM,IPP,PD分别是多少?)

      TVS连接方式如何?

  

  • AB端并没有内置TVS,并且在datasheet中Figure18中有给出design procedure。建议外面加上TVS,并且Table 4也给出了参考型号,是Littelfuse公司的SMBJ43CA:Bidirectional 600-W Transient Suppressor.可以参考一下。
