The absolute max ratings in the BF70x datasheet state -0.33V to 3.60V. Does this mean that BF70x inputs can be driven by 3.3V logic, even when its VDD_EXT is running from 1.8V with no issues of latchup or forward biasing protection diodes?
BF70x products should only be driven by 3.3V logic if VDD_EXT = 3.3V.
My VDD_EXT is 1.8V. Is it safe to drive inputs with 2.5V logic? If not, what is the limit? VDD_EXT+0.?V
