MC74VHCT74A Dual D-Type Flip-Flop with Set and Reset The MC74VHCT74A is an advanced high speed CMOS Dtype flipflop fabricated with silicon gate CMOS technology. It achieves high speed operation similar to equivalent Bipolar Schottky TTL MC74VHCT74A MAXIMUM RATINGS SymbolParameter Value Unit This device contains protection circuitry to guard against damage V DC Supply Voltage 0.5 to + 7.0 V CC due to high static voltages or electric V DC Input Voltage 0.5 to + 7.0 V fields. However, precautions must in be taken to avoid applications of any V DC Output Voltage V = 0 0.5 to + 7.0 V out CC voltage higher than maximum rated High or Low State 0.5 to V + 0.5 CC voltages to this highimpedance cir- I Input Diode Current 20 mA cuit. For proper operation, V and IK in V should be constrained to the out I Output Diode Current (V < GND V > V ) 20 mA OK OUT OUT CC range GND (V or V ) V . in out CC I DC Output Current, per Pin 25 mA Unused inputs must always be out tied to an appropriate logic voltage I DC Supply Current, V and GND Pins 50 mA CC CC level (e.g., either GND or V ). CC Unused outputs must be left open.
