TXS0108E的选择问题

请问TXS0108E是否可以同时在不同的接口上使用open drain和pull push的信号,比如A1、A2接I2C,A3、A4接24M时钟信号。

另外关于datasheet中下面的描述是要求接push-pull信号时必须先工作在open drain模式下才能切到push-pull模式么?如果一直工作在push-pull模式下会不会有问题?

The TXS0108E device is a semi-buffered auto-direction-sensing voltage translator design is optimized for translation applications (e.g. MMC Card Interfaces) that require the system to start out in a low-speed open-drain mode and then switch to a higher speed push-pull mode.

比如说如果现在有一个24M的 clock信号是push pull的,而不会像SDIO的CMD那样先工作在open drain然后才会切换到push-pull,那么这么24M的clock信号是不能使用TXS0108E做电平转换的么?
