Stresses greater than those listed under ABSOLUTE MAXIMUM RAT- INGS 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 only. 3. Outputs and I/O terminals only. CAPACITANCE (TA = +25 °C, f = 1.0MHz) Symbol Parameter(1) Conditions Typ. Max.

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 ±5µA at TA = -55°C.
