TXU0102: Is B port an input?

Daisuke Higa

Part Number: TXU0102
Other Parts Discussed in Thread: TXU0202,

Hi support team.

If you check the datasheet, you will see that there is a part where the B port is expressed as an input.
This device was capable of level conversion only in a fixed direction (AtoB), right?
Could you please tell me why the following regulations exist?

Best regards,

These values are for the TXU0202, which does have an input on the B side. (It would have made sense for the TXU devices to share a datasheet.)

Hi Daisuke,

Please note that the datasheet highlights configurations for both TXU0102 and TXU0202. Hence, Clemens' feedback, thanks.

Best Regards,

Michael.

Hi Michael-san

Thank you for your reply.

However, neither I nor my customers understood the intent.
This is because the data sheet for TXU0202 exists separately.
Why not use the same datasheet?

Best regards,

Higa

Hi Higa-San,

Yes they both have separate datasheets. However, they both complement each other as the same device with flexible configurations so as to help customers know there are other available configurations, depending on the use-case.

For example, see Figure 5-1 of the TXU0102 datasheet highlighting TXU0202, thanks.

Best Regards,

Michael.
