Output Buffer Voltage
Notes:All minimum and maximum specifications are guaranteed and apply across the recommended operating conditions.
Typical values apply at nominal supply voltages and an operating temperature of 25 °C unless otherwise noted.
VDD and VDDOx can be operated at independent voltages.
Power supply sequencing for VDD and VDDOx requires that both voltage rails are powered at the same time.
