PRODUCTION DATA
The output-enable input (OE) is used to disable the outputs so the buses are effectively isolated. The output-enable pin of the TXU0x04 has VCC(MIN) circuitry, which allows the OE pin to operate with the lower supply voltage. The Over-Voltage Tolerant Inputs feature allows the OE pin to operate with the higher supply voltage. This combination means that the enable pin can be referenced to either VCCA or VCCB supply. Multiple permutations of each device are possible since the controller can be placed on either the A or B port and can still control the enable pin.
