TXS0102: open-drain or push-pull

1.The circuit design is as follows.

Looking at the circuit, is the design in push-pull driving mode? If not, what adjustments need to be made?

2. How to distinguish which drive mode it is?(open-drain or push-pull)

Amy Luo：

您好，

TXS0102 datasheet 中描述的 open-drain or push-pull是指驱动TXS0102 输入的接口类型，如果您应用的信号是I2C，那么驱动TXS0102 输入的接口类型就是open drain，因为I2C的接口类型就是open drain。

上拉电阻对输出电压的影响建议您查看下面文档1.2章节：

Effects of pullup and pulldown resistors on TXS and TXB devices (Rev. A)

Roy Hsieh 说：2. How to distinguish which drive mode it is?(open-drain or push-pull)

您使用驱动芯片应该都有说明，比如您使用的是I2C芯片，那么其datasheet 一定会说明其接口类型为open drain。
