However, precautions must in CC be taken to avoid applications of any V DC Output Voltage (Referenced to GND) 0.5 to V + 0.5 V out CC voltage higher than maximum rated I DC Input Current, per Pin 20 mA voltages to this highimpedance cir- in cuit. For proper operation, V and in I DC Output Current, per Pin 25 mA out V should be constrained to the out I DC Supply Current, V and GND Pins 50 mA range GND (V or V ) V . in out CC CC CC Unused inputs must always be P Power Dissipation in Still Air SOIC Package 500 mW D tied to an appropriate logic voltage level (e.g., either GND or V ).
