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 shorted at one time. Duration of the short circuit test should not exceed one second.

4. The test limit for this parameter is ±5µ A at TA = -55°C.

5. Clock pin requires a minimum VIH of 2.5V.
