MC74HCT541A Octal 3-State Non-Inverting Buffer/Line Driver/ Line Receiver With LSTTL-Compatible Inputs MC74HCT541A MAXIMUM RATINGS Symbol Parameter Value Unit This device contains protection circuitry to guard against damage due V DC Supply Voltage (Referenced to GND) 0.5 to +7.0 V CC to high static voltages or electric V DC Input Voltage (Referenced to GND) 0.5 to V + 0.5 V fields. However, precautions must be in CC 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 in circuit. For proper operation, V and in I DC Output Current, per Pin 35 mA out V should be constrained to the out range GND (V or V ) V . I DC Supply Current, V and GND Pins 75 mA in out CC CC CC Unused inputs must always be tied P Power Dissipation in Still Air SOIC Package 500 mW D to an appropriate logic voltage level (e.g., either GND or V ). Unused T Storage Temperature Range 65 to +150 C CC stg outputs must be left open. T Lead Temperature, 1 mm from Case for 10 Seconds 260 C L (SOIC Package) 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.
