NOTES:

2574 tbl 05

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. This parameter is guaranteed but not tested.

5. The test limit for this parameter is

± 5µA at TA = –55°C.

NOTE:

NOTES:

1. Stresses greater than those listed under ABSOLUTE MAXIMUM RATINGS

may cause permanent damage to the device. This is a stress rating only

and functional operation of the device at these or any other conditions

above those indicated in the operational sections of this specification is

not implied.

Exposure to absolute maximum rating conditions for

extended periods may affect reliability. No terminal voltage may exceed

VCC by +0.5V unless otherwise noted.

2. Input and VCC terminals.

3. Output and I/O terminals.
