I would like to convert the 1’8V from the I/O expansion port to 3’3V or 5V, so I have been seeking on Internet and I found two options:
- TXS0108E: 8-Bit Bidirectional Voltage-Level Translator For Open-Drain And Push-Pull Application
- TXB0108: 8-Bit Bidirectional Voltage-Level Translator with Auto Direction Sensing and +/-15-kV ESD Protect
But I have a couple of questions:
1.- For the I2C and SPI should I use the TXS0108E (For Open-Drain And Push-Pull)
2.- For the rest of the pins should I use the TXB0108
Thank you for your comments.
