Vdd
No load condiꢀon, f = 20 MHz, Vdd = 2.5V, 2.8V, 3.0V or 3.3V
No load condiꢀon, f = 20 MHz, Vdd = 1.8V
ST = GND, Vdd = 3.0V or 3.3V, Output is Weakly Pulled Down
ST = GND, Vdd = 2.5V or 2.8V, Output is Weakly Pulled Down
ST = GND, Vdd = 1.8V, Output is Weakly Pulled Down
All supply voltage opꢀons
20% - 80% Vdd = 2.5V, 2.8V, 3.0V or 3.3V
20% - 80% Vdd = 1.8V
20% - 80% Vdd = 2.25V - 3.63V
IOH = -4 mA (Vdd = 3.0V or 3.3V) IOH = -3 mA (Vdd = 2.8V and Vdd =
