MC74HC03A Quad 2-Input NAND Gate with Open-Drain Outputs HighPerformance SiliconGate CMOS The MC74HC03A is identical in pinout to the LS03. The device inputs are compatible with Standard CMOS outputs with pullup MC74HC03A MAXIMUM RATINGS Symbol Parameter Value Unit This device contains protection circuitry to guard against damage V DC Supply Voltage (Referenced to GND) 0.5 to + 7.0 V CC due to high static voltages or electric V DC Input Voltage (Referenced to GND) 0.5 to V + 0.5 V in CC fields. However, precautions must V DC Output Voltage (Referenced to GND) 0.5 to V + 0.5 V be taken to avoid applications of any out CC voltage higher than maximum rated I DC Input Current, per Pin 20 mA in voltages to this highimpedance cir- I DC Output Current, per Pin 25 mA out cuit. For proper operation, V and in I DC Supply Current, V and GND Pins 50 mA V should be constrained to the CC CC out range GND (V or V ) V . in out CC P Power Dissipation in Still Air SOIC Package 500 mW D Unused inputs must always be TSSOP Package 450 tied to an appropriate logic voltage T Storage Temperature 65 to + 150 C stg level (e.g., either GND or V ). CC Unused outputs must be left open. T Lead Temperature, 1 mm from Case for 10 Seconds C L SOIC or TSSOP Package 260 Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect device reliability.
