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. Symbol Parameter Rating V Supply Voltage 0.5V to +7.0V CC DC Input Diode Current I IK V = 0.5V 20mA I V = V + 0.5 +20mA I CC DC Input Voltage 0.5V to V + 0.5V V I CC I DC Output Diode Current OK V = 0.5V 20mA O = V + 0.5V +20mA V O CC V DC Output Voltage 0.5V to V + 0.5V O CC I DC Output Source or Sink Current 50mA O or I DC V or Ground Current per Output Pin 50mA I CC GND CC Storage Temperature 65C to +150C T STG T Junction Temperature 140C J Recommended Operating Conditions 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.
