    Part Number: TXS0108E Hello When connecting TXS0108E I/Os to open drain output device, the external pull-up resistor is required, or it is not required since TXS0108E has RPUA/B internally? Best regards, K.Hirano

    Part Number: TXS0108E Hi,Johnny 我们的应用场景如下, 测试到的波形如下: 蓝色为A-PORT输入,黄色为B-PORT输出 理论上黄色波形应为高电平3.3V的方波,但实测高电平为2.5V左右,上升沿有瞬间冲到3.3V左右然后回落2.5V; 请帮忙确认下为何会出现这种情况?这种情况是否正常?谢谢!
