I've used this circuit before to do logic level conversion. The diagram is labeled to reflect I2C however I am using it for UART.
Usually my scenarios have been where the low side is 3.3v and the high side is 5v and this circuit has always been fine.
Currently I have a scenario where the low side will be 3.3v and the high may be 5v or 3.3v. I'm wondering if this circuit is still ok in this case.
Any comments are appreciated.
