II have VCCA at 3.3 abd VCCB at 5.0 and am implementing a SPI interface. from a PC with SPI to a SPI device that is 3.3V logic.
I inadvertently connected the VCCB (5.0V) to the OE pin -- have left it that way for several hrs.
Per the data sheet, the OE pin is "referenced to the VCCA" -- did I damage the chip?
