Hi team,

Do we need to add pull-up resistors for terminal A or B? Thanks!

    Hi Sam,,

    CB3T device is a down translator

    The way the part works is it is an N-channel which will output Vcc-1v. There is an internal pullup type circuit that uses the input signal to pull it up to the Vcc level. That is why the input must be 1V higher than Vcc.
