For Max. or Min. conditions, use appropriate value specified under Electrical Characteristics for the applicable device type. 2. Typical values are at Vcc = 3.3V, +25°C ambient and maximum loading. 3. Not more than one output should be shorted at one time. Duration of the test should not exceed one second. 4. This parameter is guaranteed but not tested. 5. VOH = VCC – 0.6V at rated current. Capacitance (TA = 25°C, f = 1 MHz) Parameters(1) Description Test Conditions Typ. Max.
