TXS0102: Schematics Review

Mithun P

Part Number: TXS0102

Tool/software:

I would like to convert I2C signals logic levels

Case 1) From logic 3.3V to 2.5V & I2C signals from MCU.

Case 2) From logic 1.8V to 2.5V & I2C signal from FPGA (Pull ups added near FPGA side) Via Board to Board Connector and then connected to TXS part input.

Kindly review the above schematics and please let me know any changes required.

Additionally can we use the TXS0102DQER part for GPIO (Reset ) Level Translation from 3.3V to 2.5V?

The TXS requires that VCCA is not larger than VCCB. The TXS already has internal pull-up resistors. Otherwise, looks OK.

The TXS can be used for GPIOs, if you can live with the internal pull-up resistors.

Hi Mithun,

VCCA <= VCCB should be followed for proper operation of the device, and external pullups is suggested to be removed as TXS0102 includes internal 10kohm pullups. Aside from this, schematic looks OK.

Regards,

Jack
