NOTES:
1. For conditions shown as Max. or Min., use appropriate value specified under Electrical Characteristics for the applicable device type.
2. Typical values are at Vcc = 5.0V, +25°C ambient.
3. Not more than one output should be tested at one time. Duration of the test should not exceed one second.
4. Pins with Bus-hold are identified in the pin description.
5. The test limit for this parameter is
±
5µA at T
A
= –55°C.
6. Does not include Bus-hold I/O pins.
