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

6. Does not include Bus Hold I/O pins.
