Absolute Maximum Ratings
Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be
operable above the recommended operating conditions and stressing the parts to these levels is not recommended.
In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability.
The absolute maximum ratings are stress ratings only.
Recommended Operating Conditions(5)
The Recommended Operating Conditions table defines the conditions for actual device operation. Recommended
operating conditions are specified to ensure optimal performance to the datasheet specifications. Fairchild does not
recommend exceeding them or designing to absolute maximum ratings.
Notes:
2. When outputs are in OFF-STATE or when VCC = 0V.
3. HIGH or LOW state. IOUT absolute maximum rating must be observed.
4. VOUT < GND, VOUT > VCC (outputs active).
5. Unused inputs must be held HIGH or LOW. They may not float.
