MC74HC390A Dual 4-Stage Binary Ripple Counter with 2 and 5 Sections HighPerformance SiliconGate CMOS MC74HC390A MAXIMUM RATINGS SymbolParameter 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 out CC be taken to avoid applications of any 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 those listed in the Maximum Ratings table may damage the device. If any of these limits are exceeded, device functionality should not be assumed, damage may occur and reliability may be affected.
