Part Number: TXB0108
Other Parts Discussed in Thread: TXB0106, TXB0304

Dear team,

My customer use TXB0108 for SDIO interface and they face communication issue. So they are seeking higher speed's alternative solution.The purpose of using TXB0108 is that SDIO data lines requires isolation. Could you please let me know if we have suitable part for my customer? Requirements as below.

1. Auto Bi-directional

2. SDIO interface use, Clock > 50MHz.

3. ICCA+ICCB do not have big difference than TXB0108YZPR. (save power)

4. package size do not have big difference than TXB0108YZPR.

5. 3.3V to 3.3V.

6. minimum 6 bits.

Regards,

Polly

The two sides of the TXB are not isolated (it's a level translator, not an isolator).

What exactly do you mean with "isolation"?

Polly,

What is the clock data rate requirement? you have mentioned >50Mhz, but do you have any specific number?
We have the TXB0106 device supporting 6 channels, 100Mbps 3.3V but comes in RGY package. would this work?

For faster data rates upto 140Mbps, the TXB0304 can be considered.
What is the purpose of the application if there is no translation requirement?
