Part Number: TXS0108E-Q1

Hi Team,

My customer would like to use TXS0108E-Q1, while the low level input voltage is 0-0.15V, their MCU output (output to TXS0108) low level voltage is 0-0.4V. Is there any issue? If yes, could you recommend an alternative one? thanks!

Regards,

The V_IL limit is not a requirement of the TXS itself, but needed to reach the specified V_OL; see [FAQ] Why are the TXS01xx VIH/VIL specifications so stringent?

You can use the TXS with any MCU, but a higher voltage of the input signal will result in a higher voiltage of the output signal.

Please note that 0.4 V is specified for a certain output current; if the actual current is smaller, the voltage will be lower.
