Hi Jens,

Thank you for posting to E2E! ISOW784x devices do not support Vcc = 3.3V to Viso = 5V operation at this time. May I contact you at the email address associated with your myTI account and follow up regarding this topic?

Respectfully,
Manuel Chavez

Will you have in the future TTL-Level input for Vcc = 5.0V ?

Hi Jens,

Our ISOW7841A-Q1 device has the ability to "boost" a 3.3V Vcc input to 5V on Viso output. Please allow me to follow up with you via email regarding "boost" mode for ISOW7840.

Thank you,
Manuel Chavez
